[modeller_usage] 'environ' is not defined error

[Sajeewa Pemasinghe <>]

Hi everyone,

I am working on the tutorial  http://salilab.org/modeller/wiki/Missing%20residues

I am trying to run the script 1qg8_getseq.py which has 

# Get the sequence of the 1qg8 PDB file, and write to an alignment file

code = '1qg8'

e = environ()

m = model(e, file=code)

aln = alignment(e)

aln.append_model(m, align_codes=code)

aln.write(file=code+'.seq')

I get the following error. 

  File "1qg8_getseq.py", line 4, in <module>

    e = environ()

NameError: name 'environ' is not defined

Looks like python is not reading the modeller libraries. Could you please advise how to solve this error?

Thank you
