Track statistics summary

Total genome size: 1,285,851,275
Gene count: 13,359
Bases in genes: 445,070,236
Percent genome coverage: % 34.613

Methods

The mRNAs were aligned against the Caloenas nicobarica/GCA_036013445.1_bCalNic1.hap1 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_036013445.1_bCalNic1.hap1.xenoRefGene.psl
The filtered GCA_036013445.1_bCalNic1.hap1.xenoRefGene.psl is converted to genePred data to display for this track.
