Fwd: Problem running chimera through a command script

Dear all, I have a python script that creates a .com command script for chimera and then attempts to run the chimera script.

Hi Christos, I think your error is because the “—nogui” option in your subprocess.call() has spaces before and after inside the quote marks. Take those spaces out and I bet it will work. The error seems to be trying to create the Chimera splash screen which would not happen in nogui mode. Tom

Thank you Tom. If I take out the spaces, those error messages disappear. It seems that that was a chimera issue. However, the chimera .com script is still not being executed with the subprocess.call command. I am not sure now whether this is a chimera issue or a python issue....

Hi Christos, Now I think your problem is the line script_file.close You need script_file.close() with parentheses since close is a function. Without that the command file you wrote is not closed before running chimera, and probably the file will not be written until closed because of buffering. The spaces in the --nogui option is not a Chimera bug. When you use subprocess.call() the arguments

Why do I get the error message when I attempt to run chimera through script.py? Is this a python issue or a chimera issue? I appreciate any thoughts on solving this problem....thank you,

Finishing the previous email.. the subprocess.call() arguments need to have leading and trailing whitespace removed or it is unlikely to work when calling any shell command. Only if the shell command argument is a general text string that permits leading whitespace would work. Tom

Thank you Tom. If I take out the spaces, those error messages disappear. It seems that that was a chimera issue.
However, the chimera .com script is still not being executed with the subprocess.call command. I am not sure now whether this is a chimera issue or a python issue....

I think your error is because the “—nogui” option in your subprocess.call() has spaces before and after inside the quote marks. Take those spaces out and I bet it will work. The error seems to be trying to create the Chimera splash screen which would not happen in nogui mode.

Dear all,
I have a python script that creates a .com command script for chimera and then attempts to run the chimera script. Here is the python script:
**************
#!/usr/bin/env python import re,os,sys,math, decimal, subprocess from copy import deepcopy from openeye.oechem import * from decimal import *
script_file=open("chimera_script_for_" + "ligand" +".com", 'w') script_file.write("open "+ "127D" +"\n") script_file.write("open " + "127D" +"\n") script_file.write("open "+ "ligand.pdb" +"\n") script_file.write("match #0:"+ "6" + " " + "#1:"+ "18" +"\n") script_file.write("write format pdb 2 "+ "flipped_" + "ligand" + "\n") script_file.write("stop") script_file.close print script_file.name chimera=subprocess.call(["chimera", " --nogui ", "chimera_script_for_ligand.com"]) print chimera #delete the script, leaving just the flipped ligand #os.remove(script_file.name)
*******************
When I run the script, it successfully generates the .com chimera script. However, I get the following error message:
*******************

and if I manually execute this chimera script, everything works out well:
