[modeller_usage] 'environ' is not defined error

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
