This section explains the rdf2pmfpair utility program. This program converts a radial distribution function into a potential of mean force.
The potential of mean force file is then suitable for conversion into a tabulated pair potential using the
rdf2pmfpair may be compiled using the Utility Makefile
This will create the rdf2pmfpair.x executable which can then be run from the command line.
- cd /towheebase/Utils
- make rdf2pmfpair
When you run this program from the command line it will prompt you to enter the name of the radial distribution function file that you wish to
translate. It will then ask you the number of lines of data in this file, the temperature, and the nonbonded cutoff. This utility will then output
a file named towhee_pmf that translates the radial distribution function into a potential of mean force using

PMF(r) = -kB T ln[ g(r) ]
where PMF(r) is the potential of mean force and g(r) is the radial distribution function.
