A typical cubegen run looks like the following:Ĭubegen 0 MO=HOMO benzene.fchk benzene_HOMO.cub 0 hĠ – an old memory flag (must be there, but not important) This run is simple for most users (for the rest, see formchk).įormchk benzenecation.chk benzenecation.fchkĪnd now the fun begins. cub/.cube files of orbitals, densities, electrostatic potentials, etc. chk file something that cubegen can manipulate to generate. fchk With formchkįormchk converts the data in a Gaussian checkpoint file into a formatted form which is suitable for input into a variety of visualization software.īasically, making the.

chk file (or their coefficients, anyway).Ģ. For the standard molecular orbitals, they're already saved in the. If you want additional properties cube'd, check the Gaussian Tech Document, specifically looking at the Pop keyword for most of the properties you'd want visualized (this data gets placed into the. This is performed by adding a %chk=FILENAME.chk line to the top of the input file (which, if you're a Gaussian user, you likely already know). cub/.cube files, you need a checkpoint file (.chk) from your run. I'll be demonstrating usage with benzene (C 6H 6) and the benzene cation (C 6H 6 +).

cub/.cube files for use in some kind of rendering-capable program (like VESTA or VMD) and that cubegen and formchk are in your PATH (either properly placed or by running the Gaussian install script). I am assuming for this that you're using cubegen from a terminal (not within GaussView or the like) to produce.

Specifically, I wanted to be able to take many different molecules (from hydrogen gas to big biomolecules) defined within the same-sized box for layering and presentation (different boxes for each, but all the same size). I wanted my molecule centered and bound within an arbitrarily-sized box (X,Z,Y) for making images and doing additional post-processing.

What I wanted out of cubegen that I couldn't figure out how to get: What follows below, I hope, will save you some significant frustration (and, given how little there is online that really describes the extra workings of cubegen in a clear and example'ed way, it is my expectation that this page appeared early in your search list). Fox's advice and asking Gaussian Support for assistance earlier in my endeavors. After much wailing and gnashing of teeth, I intend on taking Dr. Douglas Fox at Gaussian, Inc., who provided me with an alternative explanation of how the cubegen utility works. To begin, this post owes its existence to the efforts of Dr.
