Hi,
I ran into the following problem:

How could I fix the gff3 file?

Empty output is generated when input annotations are not in GFF3 format or 1st column of the GFF file does not match chromsome, scaffold, or contig ids in the source assembly. flo now informs user of the same if liftOver's output is empty.
