Specify the file name with the -g1 or –gff_file1 argument. Converting the GFF3 format to a format accepted by one of the three INSDC databases is a key step in the achievement of genome annotation projects. The second type of imported data is annotation files. The second type of imported data is annotation files. Providing concrete guidelines for generating GFF3, and creating a standard representation of the most common biological data types in GFF3 that would be compatible with the most commonly used tools, would provide a major increase in efficiency for all AgBioData databases. gff3_.

Run the braker with --gff3 parametrs. 23297. Note that the "Name" in output corresponds to "ID" in the original GFF3 file (based on GFF3 specification, ID for every record must be unique within a file, so this is the only identifier that can uniquely identify a specific region). 2 years ago by Ram 41k • written 9.
