Using MSAJ

MSAJ is a single window application, when you initialize it you will see a few icons, a text box and a disabled button.

It can join Multi Sequence Alignments (MSA) from FASTA and NEXUS file formats. These MSAs must have the same number of taxa with the exact same name accross all files.

To import files use the open files or the open folder buttons. The Open Files button will allow you to select more than one file, the Open Folder will allow you to select a single directory that must contain your alignment files to import.

If the files do not contain exact matches of taxa names or are corrupted in any way, MSAJ will not join the MSAs, once it will not be capable of matching taxa among files. If this happens an error will be shown in the text box.
