# Extracting geometry data from Gaussian09 geometry optimization

I want to extract the geometry for every single step of a Gaussian09 optimization from the .log file. I need the results in cartesian XYZ format, either in one file or in multiple files.

First I tried to do this in open babel, but when I run

obabel -ig09 gaussian_output.log -oxyz -m -O geometry.xyz

the program seems to fetch only the last geometry. Any other suggestions for a quick solution?

Extracting such information is typically done with scripting. You can write a simple Python (or awk, perl, ...) script to get the job done. –  Toon Verstraelen Feb 1 '13 at 6:33
