Hi.

What is the problem I'm using GAMESS-US? Works perfectly for us for years.

About jaguar however, I tried it for long time and it was not reproducible.
I would have to check my old messages about who helped me on the issue, but
we tracked the error down to different atomic radii used by jaguar if I
remember it well. For some reason I didn't report it to the mail list
myself, but it is somewhere on the archives.

On the other hand, it was more than a decade ago, maybe (possibly) jaguar
already changed this.

For yet another approach, you can use the mdgx program. See this tutorial
(need to get the webpage updated...)

advanced/tutorial28/index.php

For doing just plain old resp, you can roll with just the vacuum phase part
of the tutorial and replace lines containined "ipolq <grid file> <grid
file> <topology> <weight>" with "resp <grid file> <topology> <weight>."
This may be the most hands-on way to do it--you will have very tight
control over what goes into the fitting data, what atoms are equivalent,
and what each grid counts for.
