I find fiddling with GFF format files a real pain. How about being able to get a standard GenBank file, or accession, and GATA reading in the sequence and annotations.
I tried for hours to be able to get a real GenBank annotated sequence converted to GFF format, and for that to be read in by GATA. I never succeeded. ReadSeq puts in annotations like:
