This directory contains alignments of the following assemblies:

  - target/reference: Garter snake
    (thaSir1, Jun. 2015 (Thamnophis_sirtalis-6.0/thaSir1),
    The Genome Institute at Washington University School of Medicine (WUGSC))

  - query: Chicken
    (galGal6, Mar. 2018 (GRCg6a/galGal6),
    Genome Reference Consortium)

Files included in this directory:

  - md5sum.txt: md5sum checksums for the files in this directory

  - thaSir1.galGal6.all.chain.gz: chained lastz alignments. The chain format is
    described in .

  - "net" file that describes rearrangements between
    the species and the best Chicken match to any part of the
    Garter snake genome.  The net format is described in .

  - chained and netted alignments,
    i.e. the best chains in the Garter snake genome, with gaps in the best
    chains filled in by next-best chains where possible.  The axt format is
    described in .

  - thaSir1.galGal6.synNet.maf.gz - filtered net file for syntenic alignments
               only, in MAF format, see also, description of MAF format:

  - - filtered net file for syntenic alignments only

  - reciprocalBest/ directory, contains reciprocal-best netted chains
    for thaSir1-galGal6

The chainSwap program was used to translate galGal6-referenced chained lastz
alignments to thaSir1 into thaSir1-referenced chains aligned to galGal6.  See
the download directory goldenPath/galGal6/vsThaSir1/README.txt for more
information about the galGal6-referenced lastz and chaining process.

Chained alignments were processed into nets by the chainNet, netSyntenic,
and netClass programs.
Best-chain alignments in axt format were extracted by the netToAxt program.
All programs run after lastz were written by Jim Kent at UCSC.

If you plan to download a large file or multiple files from this directory,
we recommend you use ftp rather than downloading the files via our website.
To do so, ftp to, then go to the directory
goldenPath/thaSir1/vsGalGal6/. To download multiple files, use the "mget"

    mget <filename1> <filename2> ...
    - or -
    mget -a (to download all files in the current directory)

All files in this directory are freely available for public use.
