The mRNAs were aligned against the Caenorhabditis elegans/GCA_000975215.1_Cael_CB4856_1.0 genome using translated blat. When a single mRNA aligned in multiple places, the alignment having the highest base identity was found. Only those alignments having a base identity level within 1% of the best and at least 25% base identity with the genomic sequence were kept.
Specifically, the translated blat command is:
blat -noHead -q=rnax -t=dnax -mask=lower target.fa query.fa target.query.psl where target.fa is one of the chromosome sequence of the genome assembly, and the query.fa is the mRNAs from RefSeqThe resulting PSL outputs are filtered:
pslCDnaFilter -minId=0.35 -minCover=0.25 -globalNearBest=0.0100 -minQSize=20
-ignoreIntrons -repsAsMatch -ignoreNs -bestOverlap
all.results.psl GCA_000975215.1_Cael_CB4856_1.0.xenoRefGene.psl
The filtered GCA_000975215.1_Cael_CB4856_1.0.xenoRefGene.psl is converted to
genePred data to display for this track.
The mRNA track was produced at UCSC from mRNA sequence data submitted to the international public sequence databases by scientists worldwide.
