Hi,

I know there have been a million different and redundant questions asked concerning parallel jobs using modeller. However, after thoroughly reading through most of them (and the manual pages concerning parallel jobs) I still cannot run a modeller parallel job.

I understand that in order to run parallel modeller one has to have the python2.3 modules.

I have installed Python2.3.6 as an alternative install on my RHEL machine (the default Python for my machine is 2.7.5). However even after installing Python2.3.6 I still get the same error (no module named socket, although Python2.3.6 has the socket module --python2.7.5 does not--).

Adding a shebang with the python2.3 location in the beginning of the input changes nothing.

Here is my input:

from modeller import * from modeller.automodel import * from modeller.parallel import *

# Use 4 CPUs in a parallel job on this machine j = job() j.append(local_slave()) j.append(local_slave()) j.append(local_slave()) j.append(local_slave())

log.verbose() env = environ()

env.io.atom_files_directory = ['.', './template_struc']

# Create a new class based on 'loopmodel' so that we can redefine # select_loop_atoms class MyLoop(dopehr_loopmodel): # This routine picks the residues to be refined by loop modeling def select_loop_atoms(self): # Two residue ranges (both will be refined simultaneously) return selection(self.residue_range('278:', '284:'))

a = MyLoop(env, alnfile = 'alignment.ali', # alignment filename knowns = '2cjf_0', # codes of the templates sequence = '2cjf', # code of the target loop_assess_methods=assess.DOPE) # assess each loop with DOPE

a.starting_model= 1 # index of the first model a.ending_model = 1 # index of the last model

a.loop.starting_model = 1 # First loop model a.loop.ending_model = 1000 # Last loop model a.loop.assess_methods=(assess.DOPE, assess.GA341, assess.normalized_dope)

a.use_parallel_job(j) # Use the job for model building

a.make() # do modeling and loop refinement

And here is my error:
