Imporve sequence alignment capabilities #11
Description
The scrips em/in_development/align_CLUSTALW2.py give a simple demonstration of sequence alignment using Biopython. This could be developed to do sequence alignments of two or more structure CIF files. There is sequence information in the header of a CIF file. We don't want to know too deep into alignment, just some simple functionality that can be of use in guiding protein structural design and modeling. This would set the platform to later develop an interesting application to alignment where conserved amino acids in protein families seem to align with amino acids free energies.
