我有一个多序列文件
>abc|d017961
sequence1......
>cdf|rhtdm9
sequence2......
>ijm|smthr12
sequence3......
>abc|d011wejr
sequence4......
>stg|eethwe77
sequence5......
我想编辑文件并希望结果文件为
>abc_ABC__d017961
sequence1......
>cdf_CDF__rhtdm9
sequence2......
>ijm_IJM__smthr12
sequence3......
>abc_ABC__d011wejr
sequence4......
>stg_STG__eethwe77
sequence5......
谢谢!
