converter fastx_toolkit zcat -f '$input' | fasta_nucleotide_changer $mode -v -o $output RNA to DNA (U to T) DNA to RNA (T to U) **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 UGGAAUGUAAAGAAGUAUGUA Output DNA FASTA file (with RNA-to-DNA mode):: >cel-let-7 MIMAT0000001 Caenorhabditis elegans let-7 TGAGGTAGTAGGTTGTATAGTT >cel-lin-4 MIMAT0000002 Caenorhabditis elegans lin-4 TCCCTGAGACCTCAAGTGTGA >cel-miR-1 MIMAT0000003 Caenorhabditis elegans miR-1 TGGAATGTAAAGAAGTATGTA
