GaussSum is a software application specialized in parsing the output files of ADF, GAMESS, GAMESS-UK, Gaussian, Jaguar and PC GAMESS calculations in order to extract useful data.
The advantages of being portable
This is a portable program that can be run on your computer without having to go through installation steps. Plus, it doesn’t leave any entries in the Windows registry.
You may copy it on any USB flash drive or other devices and take it with you whenever you need to analyze the output of ADF and GAMESS files.
GaussSum adopts a clean and intuitive layout that allows you to tweak the dedicated parameters with minimal effort.
Files can be imported in the working environment using the built-in browse button, so you cannot rely on the drag-and-drop support. You are allowed to import data from OUT, LOG or ADFOUT file format, and the tool can also handle compressed log files, such as ZIP, GZ and BZ2.
Plotting and extracting data options
GaussSum is able to reveal all lines including a certain phrase, monitor the progress of SCF convergence and geometry optimization, display molecular orbital information (contributions of groups of atoms to the molecular orbits), as well as extract data about IR and Raman vibrations.
When it comes to plotting options, you are allowed to plot the density of state spectrum (as well as partial density of states when dealing with groups of atoms), crystal orbital overlap population (COOP) spectrum (in order to view data about the bonding/anti-bonding nature of an overlap between atoms/groups), UV-Vis spectrum and the circular dichroism spectrum, as well as IR and Raman spectra (you can make use of general and individual scaling parameters).
Last but not least, you can view error messages and configure several settings related to search terms, frequencies, orbitals as well as electronic transitions.
All in all, GaussSum comes with the right tools for helping you analyze, extract and monitor the progress of SCF cycles, geometry optimization, UV-Vis/IR/Raman spectra, MO levels, and MO contributions.
