Summary0001059: Clustal alignment import problem
DescriptionDear Address,
I have came across a bug. I imported Clustal alignment to MegaX, and when I clicked Phylogenetic Analysis an error meggage came up. It seems, that when I import amino acid alignment with conserved sites the stars and points are imported as a last sequence. When I delete the wrongly imported last line it works well.
Here is a video I just made from the bug: https://youtu.be/1yQsH7u7SDQ [^]
Regards,
Janos
Steps To Reproduceimport an amino acid Clustal alignment from a file (preferably with lots of conserved amino acids) and hit Phylogenetic Analysis
Additional InformationI have not tested this with nucleotides.

Hi Janos,

I am writing in response to the bug report you recently submitted regarding the MEGA software. Can you send me the .aln file you used when you encountered the problem with importing a Clustal alignment. That would help me investigate the problem. Thanks!

Hi Janos,

Thanks for sending that file. It looks like the error is caused because MEGA does not recognize that the last line in the .aln file is not sequence data but rather describes the level of conservation at each site. This will be fixed in the next release of MEGA. Until then, the workaround is to delete the last row in the Alignment Explorer or open the .aln files in a text editor and delete the last row in the file.
