Hello:

I am trying to use the following script for restrain my secondary structure:

from modeller import * from modeller.automodel import * # Load the automodel class log.verbose() env = environ() # directories for input atom files env.io.atom_files_directory = [’.’, ’../atom_files’] class MyModel(automodel): def special_restraints(self, aln): rsr = self.restraints at = self.atoms # Add some restraints from a file: # rsr.append(file=’my_rsrs1.rsr’) # Residues 20 through 30 should be an alpha helix: rsr.add(secondary_structure.alpha(self.residue_range(’20:’, ’30:’))) # Two beta-strands: rsr.add(secondary_structure.strand(self.residue_range(’1:’, ’6:’))) rsr.add(secondary_structure.strand(self.residue_range(’9:’, ’14:’)))

a = MyModel(env, alnfile='CBM-mult.ali', knowns=('2z73A','3uonA'), sequence='CBM', assess_methods=(assess.DOPE, assess.GA341))

a.starting_model= 1 a.ending_model = 1

a.make()

But it always failed with messages:

File "model_mult.py", line 36 SyntaxError: Non-ASCII character '\xe2' in file model_mult.py on line 36, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details 02-modeller/work> python test.py File "test.py", line 7 SyntaxError: Non-ASCII character '\xe2' in file test.py on line 7, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details

Does anybody have any idea where is the problem?
