## alignment.check() — check alignment for modeling

`check(io=None)`

> This command evaluates an alignment to be used for comparative modeling, by calling alignment.check_structure_structure() and alignment.check_sequence_structure().

Example: examples/commands/read_alignment.py

      # Example for: alignment.append(), alignment.write(),
      #              alignment.check()

      # Read an alignment, write it out in the 'PAP' format, and
      # check the alignment of the N-1 structures as well as the
      # alignment of the N-th sequence with each of the N-1 structures.

      from modeller import *

      log.level(output=1, notes=1, warnings=1, errors=1, memory=0)
      env = environ()
      env.io.atom_files_directory = ['../atom_files']

      aln = alignment(env)
      aln.append(file='toxin.ali', align_codes='all')
      aln.write(file='toxin.pap', alignment_format='PAP')
      aln.write(file='toxin.fasta', alignment_format='FASTA')
      aln.check()
