The RefSeq mRNAs gene track for the 31 Mar 2021 Cygnus olor/GCF_009769625.2_bCygOlo1.pri.v2
genome assembly displays translated blat alignments of vertebrate and
invertebrate mRNA in
Track statistics summary
Total genome size: 1,134,186,642
Gene count: 12,983
Bases in genes: 433,794,059
Percent genome coverage: % 38.247
The mRNAs were aligned against the Cygnus olor/GCF_009769625.2_bCygOlo1.pri.v2 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 RefSeq
The resulting PSL outputs are filtered:
pslCDnaFilter -minId=0.35 -minCover=0.25 -globalNearBest=0.0100 -minQSize=20
-ignoreIntrons -repsAsMatch -ignoreNs -bestOverlap
The filtered GCF_009769625.2_bCygOlo1.pri.v2.xenoRefGene.psl is converted to
genePred data to display for this track.
