Total genome size: 9,111,170
Gene count: 395
Bases in genes: 343,787
Percent genome coverage: % 3.773

Methods

The mRNAs were aligned against the Cryptosporidium bovis/GCF_009768925.1_ASM976892v2 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 GCF_009768925.1_ASM976892v2.xenoRefGene.psl
The filtered GCF_009768925.1_ASM976892v2.xenoRefGene.psl is converted to genePred data to display for this track.
