[modeller_usage] Problem in running Modeller 8v2

[Nagesh Chakka <>]

Hi All,
I have just installed Modeller version 8v2 and tried to run the
following script.

# Homology modelling by the allhmodel class

from modeller.automodel import *    # Load the automodel class

log.verbose()    # request verbose output
env = environ()  # create a new MODELLER environment to build this model
in

# directories for input atom files
env.io.atom_files_directory = '/home/nagesh/modelling/structure'

a = allhmodel(env,
              alnfile  = 'inputAlignment_files/xenDpl.pir',     #
alignment filename
              knowns   = '1I17',              # codes of the templates
              sequence = 'xenopusDoppel')              # code of the
target
a.starting_model= 1                 # index of the first model 
a.ending_model  = 1                 # index of the last model
                                    # (determines how many models to
calculate)
a.make()                            # do the actual homology modelling

Running the script is giving the following message. 

[nagesh@vogon ~/modelling]$ mod8v2 model_dpl_latest.top
Traceback (most recent call last):
  File "<string>", line 1, in ?
  File "/usr/lib/modeller8v2/modlib/modeller/runtop.py", line 79, in run

set_top_vars
    raise IndexError, "Variable name not recognized: %s" % varname.upper
()
IndexError: Variable name not recognized: MODELLER.AUTOMODEL


What can be the probable reason for this problem. 
Thank you in advance.
