exon names in gff file

Qihua Liang
Dear Maker development team,

I find in the gff file of exon annotation, it looks like:
ctg631  maker   exon    16239   16243   .       -       .       ID=pInfestans_00016306-RA:exon:96;Parent=pInfestans_00016306-RA;

I am wondering what does “96” mean in ID=pInfestans_00016306-RA:exon:96, it does not look like the exon numbering because not all transcripts have an exon starts from 0.

Thank you
Qihua

It’s just an iterator to ensure the ID attribute is unique for proper parent/child feature reconstruction. It’s required on the computation side and is meaningless biologically.
