使用MAFFT时遇到问题

[Jasemineyouzi]

老师您好！在使用MAFFT时出现了报错，我的是蛋白序列，选择了codon模式 问题如下 Traceback (most recent call last): File "site-packages\Bio\Seq.py", line 2588, in _translate_str File "site-packages\Bio\Data\CodonTable.py", line 385, in getitem KeyError: 'QQA'

During handling of the above exception, another exception occurred:

Traceback (most recent call last): File "codes\src\Lg_mafft.py", line 394, in run_command File "codes\src\Lg_mafft.py", line 470, in align File "codes\src\Lg_mafft.py", line 52, in init File "codes\src\Lg_mafft.py", line 105, in translate File "codes\src\Lg_mafft.py", line 91, in trim_ter File "site-packages\Bio\Seq.py", line 2605, in _translate_str Bio.Data.CodonTable.TranslationError: Codon 'QQA' is invalid

你的序列里面有 QQA，这个不是标准的密码子序列，需要先调整一下序列
