 Hi Mahdi,

I am writing in response to the bug report you recently submitted regarding the MEGA software. Could you send me the fasta file you were using when the error occurred so that I can duplicate the problem?

 Hi Mahdi,

Sorry for the late response, I have been traveling on vacation. MEGA-CC is not actually doing the sequence alignment but rather it uses the MUSCLE software. It seems that MUSCLE is not able to handle your sequence data. My suggestion is that you download MUSCLE directly from its author's website and read the documentation for working with very large datasets. In the documentation you will find suggestions for fine-tuning the alignment to work with your data. If that still doesn't work, you can contact the author of MUSCLE directly.
