[Bioperl-l] extracting sequences by id from simplealign object

[luisa pugliese]

Dear all,
    now that I solved the problems on how to put strings into simplealign
objects, I have somehow the opposite problem: I would like to extract a
sequence from the alignment. I saw that there are many ways of doing it
using the sequential number of the sequence but I didn't find how to do it
using the id. Does anybody knows if this is possible and how?
Many  thanks
Luisa
