extract exons/introns from multiple fasta files with gene sequences

Question

[ramiroricardo]

Hi all,

I have a basic question, I have several multi-fasta files one for each gene from multiple strains of a fungal species. This is the full sequence of each gene with introns and exons. I also have just the CDS for one of these fungal strains, but not for any of the others (not annotated).

For each of my multi-fasta files, I would just obtain a file with only the introns and another with the exons (CDS). Does anyone have a suggestion on how to do this?

thanks
