Note that GFF2 files and GFF3 files have the same structure, although some fields are slightly different (see reference). GTF is a much simpler, transcript-centered format and actually one of the motivations for writing gffread was to convert bloated GFF3 files into a much "leaner" GFF3 output where only the transcripts' structural information is retained -- which is what GTF was meant for as well. Gene predictions. e. Run the braker with --gff3 parametrs. 1. Share. Inputs: a GFF3 file (GFF3 file 1 or GFF3 file 2).
