[BioPython] Help on extracting title from description (Protein file parsing)

I guess I'm not exactly sure what you want to do here. The
description title and the alignment title should be the same thing,
except that the description title is shortened to fit into the
description table. So from the start I don't think I understand what
you're trying to accomplish.

You can get the title for all of the descriptions (as well as score
and e-value) with code of the following type:

for description in blast_record.descriptions:
    print description.title, description.score, description.e

Similar to how you would get the information for alignments:

for alignment in blast_record.alignments:
    print alignment.title, alignment.length

I don't know if this helps answer your questions. If you supply some
code or a better description of your problem I or someone else on
the list may be able to help more.

Hope this helps some.
