I was wondering if anyone got a chance to think about the message above that I sent: even using dummy atoms didn't allow me to perform calculations on the meshes with APBS.

I tried the suggestion above, however APBS seems to ignore the loaded meshes and generate its own meshes based on the PQR file.
Here is my APBS input file:

Thanks Nathan! I'll give that a try-LaneOn Wed, Oct 9, 2013 at 7:12 PM, Baker, Nathan <Nathan.Baker@pnnl.gov> wrote:
Hi Lane –
You should be able to load a dummy molecule to circumvent this issue.
Andrew, can you please add this to the JIRA list of future APBS features?

Hello APBS users/developers,
I'm trying to use APBS to run after loading in custom kappa, dielx/y/z, and charge meshes. I don't have a molecule to load because I only want it to use the meshes I've given it. How can I run APBS so it doesn't need a PQR or PDB file to run the electrostatics.
