[modeller_usage] loop refinement error

[albert <>]

Hello:
I try to do loop refinement by loop.py using mutiple CPU, but it doesn't work. Here is the scrips and log file. Could anybody give me some advices?

scrips:

from modeller import *
from modeller.automodel import *

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

env = environ()
log.verbose()

# directories for input atom files
env.io.atom_files_directory = ['.', '../atom_files']

# Create a new class based on 'loopmodel' so that we can redefine
# select_loop_atoms (necessary)
class dope_loopmodel(loopmodel):
    # This routine picks the residues to be refined by loop modeling
    def select_loop_atoms(self):
        # One loop from residue 19 to 28 inclusive
        return selection(self.residue_range('238:', '241:'))

m = dope_loopmodel(env,
           inimodel='backbone', # initial model of the target
           sequence='a8')               # code of the target

m.loop.starting_model= 1           # index of the first loop model
m.loop.ending_model  = 100           # index of the last loop model
m.loop.md_level = refine.slow  # loop refinement method

m.use_parallel_job(j) 
m.make()
