Hello everyone, I'm looking for a script or a tool able to merge two gff3 files, made as follows:
1) A file containing annotation data for my species
2) Another file with additional annotation (information obtained later, trying to annotate the genome against another organism in order to give a function to more genes)
The coordinate system of the two gff3s is the same since both the gff3s are produced starting from the genome of my species of interest.
Anything I found seems to be outdated, thanks in advance for your help!
