我想添加一个基于 file.txt 中的列表的额外 ID。
$ cat file.txt
ID Gene Strain-01 Strain-02 Strain-03
ID_01 pphB IMEHDJCA_03186 DIBHEKPI_01648 LLMDBGDK_00598
ID_02 group_1001 IMEHDJCA_03187 DIBHEKPI_01635 LLMDBGDK_00611
ID_03 group_1002 IMEHDJCA_03189 DIBHEKPI_01628 LLMDBGDK_00616
例如，对于 fastaStrain-01.faa文件，其IMEHDJCA_03186id 对应于Strain-01，因此我想将ID_01列 ID 的编号（来自file.txt）添加到序列的标题中，如下所示：
ID_01对应于IMEHDJCA_03186ID_02对应于IMEHDJCA_03187ID_03对应于IMEHDJCA_03189结果会是这样的：
$cat Strain-01_edited.faa
