Dear All,

I am using modeller for the first time. Before mentioning the problems I am facing, please allow me to mention my goals to be performed by modeller.

I already have a BLAST generated fasta alignment file. I need to convert the fasta alignment to PIR format, and generate the comparative model.

May I please request you to let me know how this goal can be achieved.

Moreover, after installing the modeller tarball package for ubuntu x86_64, when running the script to convert the fasta alignment to PIR I get this error.

/media/deepak/modeller/bin/modpy.sh python modeller.py Traceback (most recent call last): File "modeller.py", line 2, in <module> from modeller import * File "/media/deepak/Nourhan/deepak_research2016/NM_005343_NM_002880_RAS_RAF/modeller.py", line 3, in <module> env = environ() NameError: name 'environ' is not defined

*modeller.py*: import sys, os from modeller import * env = environ() a = alignment(env, file='NM_005343-native-protein.fasta', alignment_format='FASTA') a.write(file='NM_005343-native-protein.pir', alignment_format='PIR')

Thank you so much for your time and consideration.

Sincerely, Deepak
