Summary0004089: don't delete underscores in fasta header during alignment!
DescriptionHello,

When MEGA aligns nucleotide sequences, it erases the spaces in the header row. So, if there is a species name such as >Felis catus, in the alignment only Felis will show up.

This is a problem if I am studying multiple Felis species, i.e. Felis catus, Felis domesticus, Felis chaus, Felis margarita (the sand cat).

When I want to read the alignment file into R, it produces an error message, because these 4 species will have the same name, Felis.

Thanks, Matt
Steps To ReproduceAlign the attached fasta file (sequences.fasta), using ClustalW in the MEGA software. Double check to see that only Felis or the first name ends up in the alignment file.

Hello Monika,

I am writing in response to the error report you recently submitted to the MEGA bug tracker. Unfortunately, MEGA is a native Windows application and does not perform optimally for all Mac users. For those Mac users which experience instability issues when using MEGA, we recommend that they download the Windows version of MEGA and run it using emulation or virtualization software such as VMWareFusion.


Best regards,

Glen Stecher
