Closed:how remove stopcodons from a GFF

Question

[zion22]

Hi Thank you so much for reading this post. First of all, I would like to say that I am very new to this area of bioinformatics.

I would like to know what tool (preferably using Anaconda) I could use to remove > premature stopcodons, from a GFF file, and how I could use it properly. i executed scipio, but it showed me the next messege:

Warning: Query sequences contain gaps and/or premature stopcodons. It will be necessary to remove them if blat is run separately

And my gff file doesn´t have gaps

Thank you very much
