The RefSeq mRNAs gene track for the 28 Apr 2021 Drosophila bipectinata/GCF_018153845.1_ASM1815384v1 genome assembly displays translated blat alignments of vertebrate and invertebrate mRNA in GenBank.

Track statistics summary

Total genome size: 192,393,922
Gene count: 11,881
Bases in genes: 78,258,991
Percent genome coverage: % 40.676


The mRNAs were aligned against the Drosophila bipectinata/GCF_018153845.1_ASM1815384v1 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_018153845.1_ASM1815384v1.xenoRefGene.psl
The filtered GCF_018153845.1_ASM1815384v1.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.
