What it does

This tool converts RNA FASTA files to DNA (and vice-versa).

In RNA-to-DNA mode, U's are changed into T's.

In DNA-to-RNA mode, T's are changed into U's.

Example

Input RNA FASTA file ( from Sanger's mirBase ):

>cel-let-7 MIMAT0000001 Caenorhabditis elegans let-7
UGAGGUAGUAGGUUGUAUAGUU
>cel-lin-4 MIMAT0000002 Caenorhabditis elegans lin-4
UCCCUGAGACCUCAAGUGUGA
>cel-miR-1 MIMAT0000003 Caenorhabditis elegans miR-1

Output DNA FASTA file (with RNA-to-DNA mode):

>cel-let-7 MIMAT0000001 Caenorhabditis elegans let-7
