Alignment

Example alignment script for creating the pairwise alignment of 2GU2 and Aspa.

from modeller import *
env = environ()
# env.io.atom_files_directory = ["/apps/modeller9.9/bin/examples/commands/", "/path/to/your/files/"] ## o$
aln = alignment(env)
mdl = model(env, file='2GU2', model_segment=('FIRST:@', 'END:'))
aln.append_model(mdl, align_codes='2GU2', atom_files='2GU2')
aln.append(file='../p45381.pir', align_codes='p45381')
aln.align2d()
aln.check()
aln.write(file='aspa_2gu2-2d.ali', alignment_format='PIR')
aln.malign()
aln.check()
aln.write(file='aspa_2gu2.ali', alignment_format='PIR')
