The following script optimize.py is not working for me. It is giving an error in the line:
is giving an error in this line:

mdl.generate_topology<aln, sequence=code+'ini'>

Please suggest.

Script

env = environ()
env.edat.dynamic_sphere = True

env.libs.topology.read(file='$(LIB)/top_heav.lib')
env.libs.parameters.read(file='$(LIB)/par.lib')

code = 'unbound-scrwl'
aln = alignment(env)
mdl = model(env, file=code)
aln.append_model(mdl, align_codes=code, atom_files=code)
aln.append_model(mdl, align_codes=code+'-ini', atom_files=code+'.ini')
mdl.generate_topology(aln, sequence=code+'-ini')
mdl.transfer_xyz(aln)
mdl.build(initialize_xyz=False, build_method='INTERNAL_COORDINATES')
mdl.write(file=code+'.ini')

# Generate the restraints:
mdl.restraints.make(aln, restraint_type='stereo', spline_on_site=False)
mdl.restraints.write(file=code+'.rsr')

mpdf = mdl.energy()
