Track statistics summary

Total genome size: 1,108,218,292
Gene count: 18,114
Bases in genes: 394,036,260
Percent genome coverage: % 35.556

Methods

The mRNAs were aligned against the Abramis brama/GCA_963993115.1_fAbrBra2.1 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 
    all.results.psl GCA_963993115.1_fAbrBra2.1.xenoRefGene.psl
The filtered GCA_963993115.1_fAbrBra2.1.xenoRefGene.psl is converted to genePred data to display for this track.
