[EMBOSS] extracting sequence from a pdb file

[Jon Ison]

Hi Perdeep

You can use the program pdbparse from the "structure" EMBASSY package:
http://emboss.sourceforge.net/apps/cvs/embassy/structure/

It will read ATOM / SEQRES records and write the true (corrected) molecular
sequence (which is not an easy task!) to a file in a "clean" (easy to parse)
format, which other EMBASSY packages can then make use of.  There are various
options for controlling how it handles e.g. missing atoms, mismatches, non-amino
acid groups etc. in the original file.

It's been a long while since I tested the program on the whole of PDB though
so there are probably files it will fail for.

If you need to extract the sequence into any specified sequence format then
we could write a program for that (or something else) for the next release.
Let me know.

Cheers

Jon
