[Bioperl-l] Is there a "combine" method that would combine several sequence alignments to a single alignment?

[Gregory Baillie]

Hi.

I've attached a simple script (concatenate_alignments.pl) I wrote to concatenate alignments.

It can be a bit of a memory hog if you have long alignments or large numbers of sequences; otherwise you should be OK.

Usage:
concatenate_alignments.pl -o <output_alignment> <input_alignment_1> <input_alignment_2> <... input_alignment_n>


If you want to insert a string between the concatenated sequences, you can use the -j option (eg. -j '---').

Greg.

Hi,

No, I don't believe such a method exists. Could you describe what you are
wanting to do? Perhaps there is another way to do it.
