Hi xd_d,

It's always best to show what you tried to solve your issue, people will be more eager to solve your bugs and help you if you show some effort from your side.

Cheers,

If you have the gff3 file, you may use the GenomeTools with the following command to include intron coordinates in the gff3 file format. Later you may also convert it to gtf if you want.

gt -gff3 -retainids -addintrons input_gff3 > output_gff3

Seems the command has changed slightly. It now is as follows (the "-gff3" flag is now its own tool "gff3":

gt gff3 -retainids -addintrons input_gff3 > output_gff3

I found this script on https://github.com/riverlee/IntronGTF and used that to get the introns.

thanks all
