Description

\

The chromosome band track represents the approximate \ location of bands seen on Giemsa-stained chromosomes at\ an 800 band resolution.

\

Methods

\

A full description of the method by which the chromosome \ band locations are estimated can be found in \ Furey, T.S., and Haussler, D.,Integration of the Cytogenetic Map with the\ Draft Human Genome Sequence, Hum. Mol. Gen., 12(9):1037-1044 (2003).\

\ \

Barbara Trask, Vivian Cheung, Norma Nowak and others in the BAC Resource\ Consortium used fluorescent in-situ\ hybridization (FISH) to determine a cytogenetic location for \ large genomic clones on the chromosomes.\ The results from these experiments are the primary source of information used\ in estimating the chromosome band locations.\ For more information about the BAC Resource Consortium, see "Integration of cytogenetic landmarks into the draft sequence of\ the human genome", Nature, 409:953-958, Feb. 2001 and the accompanying web site\ Human BAC Resource.\

\ \

\ BAC clone placements in the human sequence are determined at UCSC using a combination of full BAC clone sequence,\ BAC end sequence, and STS marker information.\

Description

\ This track shows the locations of contigs of clones\ on the physical map. \ \

Method

\ In assembly versions prior to the August 2001\ freeze, this track was based on the Washington University accession\ map, which in turn was based on a fingerprint contig (FPC) map\ described in "A physical map of the human genome", Nature 409: 934-941. \

\

\ Starting with the August 2001 freeze, this track is based on tiling path (TPF) \ maps curated by the sequencing centers responsible for each chromosome. Imre\ Vastrik at the European Bioinformatics Institute merges the TPF\ maps with the FPC map, favoring the TPF map where there are conflicts.\ This step increases the clone coverage substantially over that in\ the TPF maps. This merged map is then used as the basis for the\ human genome assembly. The clone contigs in this merged map are shown in\ this track.\

Description

\

This track shows the draft assembly of the $organism genome.\ This assembly merges contigs from overlapping drafts and\ finished clones into longer sequence contigs. The sequence\ contigs are ordered and oriented when possible by mRNA, EST,\ paired plasmid reads (from the SNP Consortium) and BAC end\ sequence pairs.

\

In dense mode, this track depicts the path through the draft and \ finished clones (aka the golden path) used to create the assembled sequence. \ Clone boundaries are distinguished by the use of alternating gold and brown \ coloration. Where gaps\ exist in the path, spaces are shown between the gold and brown\ blocks. If the relative order and orientation of the contigs\ between the two blocks is known, a line is drawn to bridge the\ blocks.

Description

\

Bacterial artificial chromosomes (BACs) are a key part of many large\ scale sequencing projects. A BAC typically consists of 50-300kb of\ DNA. During the early phase of a sequencing project, it is common\ to sequence a single read (approximately 500 bases) off each end of\ a large number of BACs. Later on in the project, these BAC end reads\ can be mapped to the genome sequence. \

\

This track shows these mappings\ in cases where both ends could be mapped. These BAC end pairs can\ be useful for validating the assembly over relatively long ranges. In some\ cases, the BACs are useful biological reagents. This track can also be\ used for determining which BAC contains a given gene, useful information\ for certain wet lab experiments.\ \

A valid pair of BAC end sequences must be\ at least 50Kb but no more than 600Kb away from each other. \ The orientation of the first BAC end sequence must be "+" and\ the orientation of the second BAC end sequence must be "-".

\ \

Methods

\

BAC end sequences are placed on the assembled sequence using\ Jim Kent's blat program.

What's an Isochore

\

Isochores describe a region of a chromosome where the CG-content is\ either higher or lower than the whole genome average (42%). A CG-rich\ isochore is given a dark color, while a CG-poor isochore is a light\ color.

\

Isochores were determined by first calculating the CG-content of 100,000bp\ windows across the genome. These windows were either labeled H or L\ depending on whether the window contained a higher or lower GC-content\ than average. A two-state HMM was created in which one state represented\ GC-rich regions, and the other GC-poor. It was trained using the first 12\ chromosomes. The trained HMM was used to generate traces over all chromosomes.\ These traces define the boundaries of the isochores,\ and their type (GC-rich or AT-rich).

Description

\

\ The Known Genes track shows known protein coding genes based on \ proteins from SWISS-PROT, TrEMBL, and TrEMBL-NEW and their\ corresponding mRNAs from Genbank.\ Coding exons are displayed \ taller than 5' and 3' untranslated regions (UTR). Connecting introns \ are one-pixel lines with hatch marks indicating direction of transcription.\ Entries which have corresponding entries in PDB are colored black.\ Entries which either have corresponding proteins in SWISS-PROT or mRNAs that are \ NCBI Reference Sequences with a "Reviewed" status are colored dark blue.\ Entries which have mRNAs that are \ NCBI Reference Sequences with a "Provisional" status are colored lighter blue.\ Everything else is colored with lightest blue.

\ \

Method

\

\ All mRNAs of a species are aligned against the genome using the blat\ program. When a single mRNA aligns in multiple places, only\ the best alignments are kept. The alignments must also have \ at least 98% sequence identity to be kept. \ This set of mRNA alignments is further reduced by keeping only those mRNAs that \ are referenced by a protein in SWISS-PROT, TrEMBL, or TrEMBL-NEW.

\

\ Among multiple mRNAs referenced by a single protein, the best mRNA is chosen based on \ a quality score, which depends on its length, how good its translation matches \ the protein sequence, and its release date.\ The list of mRNA and protein pairs are further cleaned up by removing \ short invalid entries and consolidating entries with identical CDS regions.

\

\ Finally, RefSeq entries which are derived from DNA sequences instead of \ mRNA sequences are added.

\ Slam predicts coding exons and conserved noncoding regions in a pair of homologous DNA sequences, incorporating both statistical sequence properties and degree of conservation in making the predictions. The model is symmetric and the same gene structure (with possibly different exon lengths) is predicted in both sequences.\ \

\ The symmetry of the model gives it a higher degree of accuracy for regions where the true underlying gene structures contain the same number of coding exons, in cases where this is not true, or when one of the sequences is of lower quality and contains in-frame stop codons, the resulting predictions tend to have lower accuracy.\ \

\

Methods

\

\ Geneid is a program to predict genes in anonymous genomic sequences designed \ with a hierarchical structure. In the first step, splice sites, start and stop \ codons are predicted and scored along the sequence using Position Weight Arrays \ (PWAs). Next, exons are built from the sites. Exons are scored as the sum of the \ scores of the defining sites, plus the the log-likelihood ratio of a \ Markov Model for coding DNA. Finally, from the set of predicted exons, the gene \ structure is assembled, maximizing the sum of the scores of the assembled exons. \

\

\ Eddy-BLAST-otherrnalib \ (non-tRNA, non-snoRNA noncoding RNAs with Genbank entries\ for the human gene.):
\ Wublastn 2.0 [15 Apr 2002]\ with options: "-kap -cpus=1 -wordmask=seg -W=8 -E=0.01 -hspmax=0\ -B=50000 -Z=3000000000". Exceptions to this are:\

\

\ The score field contains the blastn score. \ Used 41 unique miRNAs, and 29 other ncRNAs as queries.\ Any hit >=95% full length and >=95% identity is annotated as a \ "true gene".\ Any other hit with P <= 0.001 and >= 65% identity is annotated\ as a "related sequence". An exception to this is: all miRNAs consist \ \ of 16-26bp sequences in Genbank \ and are only annotated if 100% full length and 100% identity. \ miRNAs consist of Let-7 from Pasquinelli et al., \ Nature (2000) 408:86; 40 from Mourelatos et al., Gene & Dev (2002) \ 16:720.

Using the Filter

\

The track filter can be used to change the color or include/exclude a subset of individual \ items within a track. This is helpful when many items are shown in the track\ display, especially when only some are relevant to the current task. To use the\ filter:\

    \
  1. Enter a value in one or more of the text boxes to filter the mRNA display. For\ example, to apply the filter to all liver mRNAs, type "liver" in the \ tissue box. For a list of permissible filter values, consult the non-positional table in\ the Table Browser that corresponds to the factor on which you wish to filter. For\ example, the non-positional table "tissue" contains all of the types of tissues\ that can be entered into the tissue text box. Wildcards can also be used in the\ filter.\
  2. If filtering on more than one value, choose the desired combination\ logic. If "and" is selected, only mRNAs that match all of the filter criteria will\ be highlighted. If "or" is selected, mRNAs that match any 1 of the filter criteria\ will be highlighted.\
  3. Choose the color or display characteristic that will be used to highlight or\ include/exclude the filtered items. If "exclude" is chosen, the browser will not \ display mRNAs that match the filter criteria. If "include" is selected, the browser \ will display only those mRNAs that match the filter criteria.\

Description

\

The Spliced EST track displays Expressed Sequence Tags \ (ESTs) from Genbank that show signs of splicing when\ aligned against the genome. By requiring splicing, the level \ of contamination in the EST databases is drastically reduced\ at the expense of eliminating many genuine 3' ESTs.\ For a display of all ESTs (including unspliced), see the \ $Organism EST track.

\ \

Expressed sequence tags are single read (typically\ approximately 500 base) sequences which usually\ represent fragments of transcribed genes. Aligning \ regions (usually exons) are shown as black boxes \ connected by lines for gaps (usually spliced out introns). \ In full display mode, arrows on the introns\ indicate the direction of transcription. In the\ December 2001 assembly and later, this direction is\ taken by looking at the splice sites. In previous\ assemblies, the direction of transcription was taken from \ the Genbank annotations, which frequently were inaccurate.

\ \

Method

\

To make an EST, RNA is isolated from cells and reverse\ transcribed into cDNA. Typically, the cDNA is cloned\ into a plasmid vector, and a read taken from the 5'\ and/or 3' primer. For most - but not all - ESTs, the\ reverse transcription is primed by an oligo-dT, which\ hybridizes with the poly-A tail of mature mRNA. The\ reverse transcriptase may or may not make it to the 5'\ end of the mRNA, which may or may not be degraded.

\ \

In general, the 3' ESTs mark the end of transcription\ reasonably well, but the 5' ESTs may end at any point\ within the transcript. Some of the newer cap-selected\ libraries are starting to hit transcription start\ reasonably well. Before the cap-selection techniques\ emerged, some projects used random rather than poly-A\ priming in an attempt to get sequence distant from the\ 3' end. These projects were successful at this, but as\ a side effect also deposited sequences from unprocessed\ mRNA and perhaps even genomic sequences into the EST databases.\ (Even outside of the random-primed projects, there is a\ degree of non-mRNA contamination.) Because of this, a\ single unspliced EST should be viewed with considerable\ skepticism. However, because the $organism 3' UTRs are quite\ long, the splicing requirement does eliminate many genuine 3'\ ESTs.

\ \

To generate this track, $organism ESTs from Genbank are aligned \ against the genome using the blat program. Note that the maximum intron length\ allowed by blat is 500,000 bases, which may eliminate some ESTs with very \ long introns that might otherwise align. When a single \ EST aligns in multiple places, the alignment having the \ highest base identity is found. Only alignments that have \ a base identity level within 1% of the best are kept. \ Alignments must also have at least 93% base identity to be kept.

Description: Serial Analysis of Gene Expression (SAGE)\ is a quantative measurement gene expression. Data is presented for every cluster contained \ in the browser window and the selected cluster name is highlighted in red. All data is from \ the repository at the SageMap \ project downloaded Jul 26, 2002. Selecting the UniGene cluster name will display SageMap's page for that cluster.\

Brief Methodology: SAGE counts are produced \ by sequencing small "tags" of DNA believed to be associated with a \ gene. These tags are produced by attatching poly-A RNA to oligo-dT \ beads. After synthesis of double stranded cDNA transcripts are \ cleaved by an anchoring enzyme (usually NIaIII). Then small tags are \ produced by ligation with a linker containing a type IIS restriction \ enzyme site and cleavage with the tagging enzyme (usually BsmFI). The \ tags are then concatenated together and sequenced. The frequency of each \ tag is counted and used to infer expression level of transcripts that can \ be matched to that tag. All SAGE data presented here was mapped to UniGene \ transcripts by the SageMap \ project at NCBI .

Description

\

\ This track shows the boundaries of genes and the direction of\ transcription as deduced from clustering spliced ESTs and mRNAs\ against the genome. When there are many spliced variants\ of the same gene, this track shows the variant that\ spans the greatest distance in the genome.

\ \

Method

\

\ ESTs and mRNAs from Genbank are aligned against the genome\ with the blat program, and filtered to keep only those alignments\ that have at least 97.5% base identity within the \ aligning blocks. When multiple alignments occur, only the\ alignments with a percentage identity within 0.2% of the\ best alignment are kept. ESTs that align without any\ introns are discarded. Blocks that are less than 130 bases\ and are not next to an intron are discarded. Blocks smaller\ than 10 bases are discarded. The orientations of the \ ESTs and mRNAs are deduced from the GT/AG splice sites\ at the introns, and ESTs and mRNAs with overlapping blocks\ on the same strand are merged into clusters. Only the\ extent and orientation of the clusters are shown here.\

Description

\

\ CpG islands are associated with genes, particularly housekeeping\ genes, in vertebrates. CpG islands are typically common near\ transcription start sites, and may be associated with promoter\ regions. Normally a C (cytosine) base followed immediately by a G (guanine) base (a CpG) is rare in\ vertebrate DNA because the C's in such an arrangement tend to be\ methylated. This methylation helps distinguish the newly synthesized\ DNA strand from the parent strand, which aids in the final stages of\ DNA proofreading after duplication. However, over evolutionary time\ methylated C's tend to turn into T's because of spontaneous\ deamination. The result is that CpG's are relatively rare unless\ there is selective pressure to keep them or a region is not methylated\ for some reason, perhaps having to do with the regulation of gene\ expression. CpG islands are regions where CpG's are present at\ significantly higher levels than is typical for the genome as a whole.\

\ \

Method

\

\ CpG islands are predicted by searching the sequence one base at a\ time, scoring each dinucleotide (+17 for CG and -1 for others) and\ identifying maximally scoring segments. Each segment is then\ evaluated to determine GC content (>=50%), length (>200), and ratio of\ observed proportion of CG dinucleotides to the expected proportion on\ the basis of the GC content of the segment (>0.6). \

The authors have provided a\ web supplement \ where more data and experimental description can be obtained. cDNA\ probes were placed on the draft human genome using genebank sequences\ referenced by the IMAGE clone ids. \ \

The data are shown in a tabular format in which each column of\ colored boxes represents the variation in transcript levels for a\ given cDNA across all of the array experiments, and each row\ represents the measured transcript levels for all genes in a single\ sample. The variation in transcript levels for each gene is\ represented by a color scale, in which red indicates an increase in\ transcript levels, and green indicates a decrease in transcript\ levels, relative to the reference sample. The saturation of the color\ corresponds to the magnitude of transcript variation. A black color\ indicates an undetectable change in expression, while a gray box\ indicates missing data.\ \

Description

\

Expression data from Rosetta Inpharmatics.\ See the paper "Experimental Annotation of the Human Genome Using Microarray Technology"\ Nature Feb. 2001, vol 409 pp 922-7 for more\ information. Briefly, Rosetta created DNA probes for each exon as\ described by the Sanger center for the October 2000 draft of the\ genome and used them to explore expression leves over 69 different\ experiments. As in the original paper exons are labeled according to\ contig name, relative position in the contig, and whether they were\ predicted (pe) or confirmed (true->te) exons at the time of\ publication. For example, AC000097_256_te is the 256th exon on\ AC000097 predicted by Genescan which was confirmed\ independently. Hybridization names refer to the sources of the two\ mRNA populations used for the experiment.\ Please note: in the browser window the hybridization names\ are too long to fit and have been abbreviated. Also, the ratios\ were inverted as of Feb 12, 2002 to conform with standard microarray\ conventions of having the experimental sample in the red (cy5) channel\ and the reference sample in the green (cy3) channel.\ \

Display Options

\ The track can be configured with a few different options:\ \
Reference Sample: This option is only valid when the track is displayed in\ full. It determines how the 69 different experiments are displayed. The\ options are:\
    \
  • All Experiments: Display the data for each experiment one\ row per experiment.
  • \
  • Common Reference and Other: Displays a summary value for all the\ experiments done with a common pooled reference sample, and another summary value for \ the rest of the experiments.
  • \
  • Common Pool: Only displays experiments which were performed using a \ common pooled reference sample.
  • \
  • Other: Only displays experiments which were not performed using a common\ pooled reference sample.
  • \
\ \ Exons Shown: Probes on the microarrays correspond to gene\ predictions on chromosome 22, some of which were confirmed by known\ genes, others are predictions. This option determines whether data is\ shown for probes corresponding to confirmed, predicted, or all exons\ are shown.\ \
Color Scheme: Data are presented using two color false\ display. By default the Brown/Botstein colors of red -> positive log\ ratio, green -> negative log ratio are used. However, blue can be\ substituted for green for those who are color blind. Gray values\ indicate missing data. Please note that due to technical limitations\ the details page will have many more color shades possible than those used\ on the browser image and thus may not match exactly.\ \

Description

\ \

Transcriptome data for chromosomes 21 and 22 from Affymetrix, as described in \ "Large-Scale Transcriptional Activity in Chromosomes 21 and 22",\ Kapranov, P., Cawley, S. E., Drenkow, J., Bekiranov, S, Strausberg,\ R. L., Fodor, S.P.A. and Gingeras, T.R.. In general, the data presented\ is the perfect match - mis-match value. Different experiments were\ normalized by setting the average value to be the same for each\ chip. Replicates for different cell types were averaged together to\ produce the data seen in "full" mode for each cell type. In dense\ mode, or at the top of the track in full mode, "Transcriptome" displays\ the maximum value over all experiments for that probe, the idea being\ to paint as many transcribed regions as possible. \ \

To present a more\ interpretable display when zoomed out, averages have been precalculated\ over the chromosome at two different resolutions in addition to the\ raw data. For example, when zoomed out, there may appear to be a peak at\ the center of a gene rather than a signal at every exon. Zooming in\ will reveal the "raw" data for that region.\ \

Description

\

This track displays translated alignments of 728 million bases of Tetraodon nigroviridis \ whole genome shotgun reads vs. the draft $organism genome. Areas painted by\ this track are quite likely to be coding regions.

\ \

Methods

\

The alignments were done \ with blat in translated protein mode requiring 2 nearby 4-mer matches\ to trigger a detailed alignment. The human\ genome was masked with RepeatMasker and Tandem Repeat Finder before \ running blat.

Description

\

\ This track displays the conservation between the human and mouse genomes for \ 50bp windows in the human genome that have at least 15 bp aligned to\ mouse. The score for a window reflects the probability that the\ level of observed conservation in that 50bp region would occur by\ chance under neutral evolution. It is given on a logarithmic scale,\ and thus it is called the "L-score". An L-score of 1 means there is a\ 1/10 probability that the observed conservation level would occur by\ chance, an L-score of 2 means a 1/100 probability, an L-score of 3\ means a 1/1000 probability, etc. The L-scores display as\ "mountain ranges". Clicking on a mountain range, a detail page is\ displayed from which you can access the base level alignments, both\ for the whole region and for the individual 50bp windows.\

\ \

Methods

\

\ Genome-wide alignments between human and mouse were produced by\ blastz. A set of 50bp windows in the human genome were determined\ by scanning the sequence, sliding 5 bases at a time, and only those\ windows with at least 15 aligned bases were kept. For each window,\ a conservation score defined by\

\

\ S = sqrt(n/m(1-m))(p-m)\
\
\ was calculated, where n is the number of aligning bases in the\ window, p is the percent identity between human and mouse for these\ aligning bases, and m is the average percent identity for aligned\ neutrally evolving bases in a larger region surrounding the 50bp\ window being scored. Neutral bases were taken from ancestral repeat\ sequences, which are relics of transposons that were inserted before\ the human-mouse split. To transform S into an L-score, the empirical\ cumulative distribution function CDF(S) = P(x < S)\ is computed from the scores of all windows genome-wide, and\ the L-score is defined as\

\
\ L = -log_10(1 - CDF(S)).\
\
\
\ The L-score\ provides a frequentist confidence assessment. A Bayesian\ calculation of the probability that a window is under\ selection can also be made using a mixture decomposition of\ the empirical density of the scores for all windows\ genome-wide into a neutral and a selected component. Details\ are given in a manuscript in preparation. The results are\ summarized in the table below.\

Using the Filter

\

The track filter can be used to configure some of the display characteristics\ of the track. \

    \
  • Interpolation: This attribute determines whether the data samples are \ displayed as discreet points on the track (the "Only samples" option) or are \ connected by a line (the "Linear interpolation" option).\
  • Fill Blocks: When the on button is selected in this option, the area \ underneath the sample points or line is filled in with gray.\
  • Track Height: Type in a new value to adjust the track height in pixels to best suit your screen display. \
  • Vertical Range: Type in a new min or max value to adjust the portion of the track's vertical\ range that is displayed. Range units are marked by pale blue horizontal lines.\
  • Maximum Interval to Interpolate Across: This attribute sets the maximum gap\ between alignments that will be spanned when the Linear Interpolation \ attribute is selected. Type in a new value to increase or decrease the interval.\

\ When you have finished configuring the filter, click the Submit button.\ \

\ Slam predicts coding exons and conserved noncoding regions in a pair of\ homologous DNA sequences, incorporating both statistical sequence properties\ and degree of conservation into predictions. The model is symmetric and the\ same structure (with possibly different lengths) is predicted in both\ sequences.\ \

\ The CNS (conserved non-coding sequence) predictions are ab-initio\ predictions of conserved regions that do not fit in with a gene structure.\ Thus, SLAM is not simply trying to predict conserved regions to be coding,\ but is classifying such regions according to an overall probabilistic model\ of gene structure. The set of SLAM CNS predictions is therefore highly\ enriched for conserved non-coding regions.\ \

Description

\

\ This track shows syntenous (corresponding) regions between human and mouse chromosomes. \

Methods

\

\ We passed a 100k non-overlapping window over the genome and - using the blastz best in mouse \ genome alignments - looked for high-scoring regions with at least 40% of the bases aligning \ with the same region in mouse. 100k segments were joined together if they agreed in direction and\ were within 500kb of each other in the human genome and within 4mb of each other in the mouse. \ Gaps were joined between syntenic anchors if the bases between two flanking regions agreed with \ synteny (direction and mouse location). Finally, we extended the syntenic block to include those \ areas.

Description

\ This track shows rat/$organism genomic alignments using\ a gap scoring system that allows longer gaps than traditional\ affine gap scoring systems. It can also tolerate gaps\ in both rat and $organism simultaneously. These "double-sided"\ gaps can be caused by local inversions and overlapping deletions\ in both species.\ \

Methods

\ Transposons that have been inserted since the rat/$organism\ split are removed, and the resulting abbreviated genomes are\ aligned with blastz. The transposons are then put back into the\ alignments. The resulting alignments are converted into axt format\ and the resulting axts are fed into axtChain. AxtChain organizes all \ the alignments between a single rat and a single $organism chromosome,\ into a group, and makes a kd-tree out of all the gapless subsections\ (blocks) of the alignments. Next, maximally scoring chains of these\ blocks are found by running a dynamic program over the kd-tree. Chains\ scoring below a threshold are discarded, and the remaining chains are\ displayed here.\ \

Description

\ This track shows the best rat/$organism chain for \ every part of the $organism genome. It is useful for\ finding orthologous regions and for studying genome\ rearrangement. In full mode the top level (level 1)\ chains are the largest, highest scoring chains that\ span this region. In many cases there are gaps in the\ top level chain. When possible, these are filled in by\ other chains that are displayed at level 2. The gaps in \ level 2 chains may be filled by level 3 chains and so\ forth.
\
\ In the graphical display, the boxes represent ungapped \ alignments, while the lines represent gaps. Clicking\ on a box brings up detailed information about the chain\ as a whole, while clicking on a line brings up information\ on the gap. The detailed information is useful in determining\ the cause of the gap or, for lower level chains, the genomic\ rearrangement.
\ \

Methods

\ First, chains are derived from blastz alignments as\ described in the details pages of the chain tracks\ and sorted so that the highest scoring chain in the\ genome is first. The program chainNet then places\ chains one at a time, trimming them as necessary to\ fit into section that is not already covered by \ a higher scoring chain. During this process, a\ natural hierarchy emerges where chains that fill gaps\ in a previous chain are considered underneath the\ previous chain. The program netSyntenic fills in\ information about the relationship between upper\ and lower level chains, including whether a lower level\ chain is syntenic with the higher level chain, whether\ it is inverted with respect to the higher level chain,\ and so forth. The program netClass then fills in \ how much of the gaps and chains are filled with N's\ (sequencing gaps) in one or both species, how much\ is filled with transposons inserted before and after\ rat and $organism diverged, and so forth.\ \

Description

\ \

This track shows locations of Single Nucleotide Polymorphisms\ detected primarily by looking at overlaps between clones that cover\ the same region of the genome.

\ \

The SNPs in this track include all of the polymorphisms that can be\ mapped against the current assembly. These include known point\ mutations (Single Nucleotide Polymorphisms), insertions, deletions,\ and segmental mutations from the current build of \ dbSNP. \

\

\ There are three major cases that are not mapped and/or annotated:\

    \
  • \ Submissions that are completely masked as repetitive\ elements. These are dropped from any further computations. This set of\ refSNPs is dumped in chromosome "rs_chMasked" on the dbSNP ftp site.\
  • \ Submissions that are defined in a cDNA context with extensive\ splicing. These SNPs are typically annotated on refseq mRNAs through a\ separate annotation process. Effort is being made to reverse map these\ variations back to contig coordinates, but that has not been\ implemented. For now, you can find this set of variations in\ "rs_chNotOn" on the dbSNP ftp site.\
  • \ Submissions with excessive hits to the genome. Variations with\ 3+ hits to the genome are not included in the tracks, but are available in\ "rs_chMulti" on the dbSNP ftp site.\
\

\

The heuristics for the non-SNP variations (i.e. named elements and\ STRs) are quite conservative; therefore, some of these are probably lost. This\ approach was chosen to avoid false annotation of variation in\ inappropriate locations.

Candidate Oligos for every Stanford Oligo Chip track

\

\ Oligos were chosen for every Sanger22 annotation on chr22 as\ well as about 2000 other genes. Two oligos were chosen with\ a 3' bias, two with a 5' bias, and two with no bias. For this\ purpose exons are defined to include 3' and 5' UTRs.

\ \

The strategy

\

\ These oligo selections are based on the following ideas:\

    \
  • Oligos should have minimum secondary structure as\ they must be available for hybridization.
  • \
  • Oligos should be unique in genome if possible. No\ repeats, should not Blat or Blast other places in genome.
  • \
  • If using oligo-dT for RT-Priming oligos should be in 3' end\ of gene transcript (including UTR).
  • \
  • Oligos should have a uniform hybridization temperature if\ possible. All oligos must be hybridized at same temperature,\ want to minimize cross hybe yet maximize signal.\

\

\ Currently we don't have data to identify which parameters\ are more important than others. Also, some of these scores\ are overlapping (i.e. if tm is limited then high secondary\ structure is less likely). See below for histograms of these\ criteria.

The Algorithm

\

\

    \
  • Step through each exon at a step size proportional to the\ size of the exon examining possible oligos, excluding areas that\ are RepeatMasked.
  • \
  • Score each oligos for: Tm difference, distance from 3' end,\ secondary structure, and an Affymetrix heuristic.
  • \
  • Look through candidate probes remembering the maximum\ score for each score.
  • \
  • Each score is then normalized by dividing by the maximum\ and then the normalized scores are combined as an average and oligos\ are sorted to find the best overall score.
  • \
  • Oligos with the best combined normalized scores are blatted\ until one is found that has a blat score below a given \ threshold.
  • \
  • As oligos are chosen, candidate oligos that overlap those\ already chosen are discarded.
  • \
  • If no scores pass the blat score or not enough oligos have been\ chosen just pick oligos that have the best combined score.
  • \

\

    \
  • Tm: Formulas for calculating Tm taken from: "A unified\ view of polymer, dumbbell, and oligonucleotide DNA\ nearest-neighbor thermodynamics" John SantaLucia, Jr. PNAS, Vol\ 95, pp 1460-1465 February 1998.
  • A web version called \ Hyther exists.\
  • Secondary Structure: Calculates the Gibbs free energy of the\ best secondary structure using libraries from the RNAstructure program.
  • \
  • Affy Heuristic: 1 if oligo passes heuristics derived from that published by Affymetrix \ "Nature Biotechnology" vol. 14, Dec, '96) are satisfied, 0 otherwise. The heuristic\ is as follows:\
    \
       no more than 9 A's in window of 20 \
       no more than 9 T's in window of 20\
       no more than 8 C's in window of 20\
       no more than 8 G's in window of 20\
      \
       no more than 6 A's in window of  8\
       no more than 6 T's in window of  8\
       no more than 5 C's in window of  8 \
       no more than 5 G's in window of  8\
    
    \
  • \
  • 3' Dist: Distance from end of oligo to 3' end of target\ sequence.
  • \
  • Blat Score: Blat score of second most homologous region\ in the genome. If no inserts this is approximately the number of\ base pairs that match.

Histograms of Scores

\

\ Histograms are from the Stanford picked gene set.\ \ \ \ \ \ \ \ \ \

\ Secondary structure measured in Gibb's Free energy, higher scores are better.

\ Blat (similar to blast) histogram, lower scores are better.

\ Melting temperatures, scores over 100C do happen in algorithm.

\ Percentage GC, not used in algorithm but presented anyway.
\

\

Please note that all coordinates are relative to the '+' strand\ while all oligo sequences are 5'->3'. This means that all sequences\ displayed are part of the sense strand. So if the oligo is represented\ in the database as being on the '-' strand and starts at 1 and ends at\ 5 of 'atgcatgc' the '+' sequence of the probe would be 'tgcat' but\ that is 3'->5' on the '-' strand so the sequence in the sequence would\ be the reverse complement 'atgct'.

PATTERNHUNTER is a highly sensitive and efficient program for\ finding homologies within one, or between two DNA sequences.\ On very long sequences it runs faster than MegaBlast while\ being more sensitive than Blastn (at its default settings).

\

This track was produced by having PATTERNHUNTER index each human chromosome \ 22 and processing all mouse reads in turn, looking\ for double hits of weight 11 (using size 18 words with 7 don't cares in the\ pattern 111010011001010111) to extend from and form gapped alignments.

Display

\

This track displays alignments of the current mouse assembly (phusion.3)\ against regions of the human genome contained in an ancient copies of\ transposable elements. In this case "ancient" means that RepeatMasker's\ annotation indicates that the copy was fixed as an interspersed repeat in\ a common ancestor of human and mouse. These regions are of interest\ because they, more likely then any other region, have not been under\ functional constraint.\ Each block in the alignment is displayed as a colored block on the track\ with a line connecting all the blocks. The color of each alignment\ indicates the percent identity of aligned residues over all blocks of the\ alignment. 50% identity and below is lightly colored and the color gets\ linearly darker as the percent identity approaches 100%.\ In the alignments, lower case letters indicate that RepeatMasker annotated\ them as an interspersed repeat. Because of the high substitution rate in\ the mouse lineage, the element often only was recognized in the human\ genome. The original alignments often are much longer, but only the region\ witin the repeat is displayed.\ \

Methods

\

The sequences were aligned with blastz (discontiguous exact seeds,\ ungapped extension, local alignments via dynamic programming) and\ postprocessed for single coverage.\ \
