Start with basename.gbw
from an ORCA computation. This method has only been tested on Windows 7, primarily because MultiWFN is challenging to execute on Linux and Mac.
- Convert to MOLDEN format via
orca_2mkl basename -molden
- Rename
basename.molden.input
tobasename.molden
(this is so MultiWFN will recognize it properly) - Run MultiWFN; load
basename.molden
- Export the reduced density gradient and "sign(lambda_2)*rho" to CUBE using the following MultiWFN commands:
a. 5 (output property in spatial region)
b. 13 (RDG)
c. 3 (high grid over entire system -- can enter custom grid for better isosurface resolution)
d. 2 (export CUBE)
