Gaussian Tools

These tools were written for Gaussian. They work well for me; they may not work for you depending on your current Gaussian version and shell configuration. Since using this scripts can have a HUGE impact on your research, please have a look at each of them to fully understand the implications of utilizing them in your work flow. That being said, I use them personally and have tested them to the best of my ability/experience. Of course, if you find a better way to do things then by all means share by opening an issue! I currently use them to extract data from output files and to tweak input files of larger jobs.

These scripts may be used individually or with one another. For example, if you are interested in the lowest imaginary frequency, you would run

g09-lowest-imaginary-frequency.zsh "foo.out"

and the pertinent data point would be output to the command line. Alternatively, if you wish to aggregate data into a csv file for further analysis with a spreadsheet program you could utilize several of the scripts together (for an example of how to integrate the individual scripts with one another, see g09-make-data and g09-generate-supporting-information). All scripts generally work in format of

g09-foo.zsh "bar.out"

with the exception of g09-mulliken-charges.zsh, which can take a second argument of the atom whose Mulliken charge you wish to obtain.

Compatibility

I typically stay on the bleeding edge of computing. I created these on OS X 10.9 and have tested them using the following:

Program	Version
zsh	>= 5.0.2
python	== 2.7.5
GNU awk	>= 4.1.0
Gaussian	== Gaussian 09, Revision C.01 (there is β support for Rev. D.01)

Future work

There are currently plans to incorporate the above abilities to output from the formchk utility Gaussian provides. The rationale is that the output from that utility will not change between revisions of Gaussian, making the scripts far more reliable, faster to use and easier to maintain.
