Ok, I modified my script as in the example.

---- (script)

from modeller import * from modeller.automodel import * from modeller.scripts import complete_pdb from modeller.parallel import *

j = job() j.append(local_slave()) j.append(local_slave())

log.verbose()

class mymodel(allhmodel): def special_restraints(self, aln): s1 = selection(self.chains['A']) s2 = selection(self.chains['B']) self.restraints.symmetry.append(symmetry(s1, s2, 1.0)) def user_after_single_model(self): self.restraints.symmetry.report(1.0)

env = environ()

env.io_atom_files_directory = './'

a = mymodel(env, alnfile = 'HpUreE.ali', knowns = 'dimerBp', sequence = 'HpUreE', assess_methods=(assess.DOPE, assess.GA341))

a.starting_model = 1 a.ending_model = 25

a.use_parallel_job(j) a.make()

# Output data ok_models = filter(lambda x: x['failure'] is None, a.outputs) key = 'DOPE score' ok_models.sort(lambda a,b: cmp(a[key], b[key])) m = ok_models[0] print "Top model: %s (DOPE score %.3f)" % (m['name'], m[key])

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

# read model file mdl = complete_pdb(env, m['name'])

# Assess with DOPE: s = selection(mdl) s.assess_dope(output='ENERGY_PROFILE NO_REPORT', file='HpUreE.best.profile', normalize_profile=True, smoothing_window=15) ---- (end)

i obtained this error:

---- (log)

---- (end)

in the .slave0 and .slave1 log file I have this error:

---- (log) Slave startup: connect to master at 127.0.1.1:59037:0:EABQEAKC Traceback (most recent call last): File "<string>", line 1, in ?

---- (end)

running Modeller in the normal way do not produce any error.

Thanks
