The problem with pdb2pqr have been solved :) Another question which I have is the calculation of the potential maps from the ensemble of the conformers (for example I want to compare potential distribution from the ensemble of the x-ray structures of one protein which were solved in different

I have a similar requirement, taking density and potential dstriutbutions fromĀ  jdftx which are written as plain binarry doubles. I use a script and some code to create an xplor file which seems to work but I have to adjust the position and scale to let it overlay the ion positions that I read

As I understood the APBs plugin which already exist in PyMol is the very efficient device for electrostatic potential calculations. 2 questions have been arisen: 1- How I could change cut-off distances for the electrostatic? E.g I'd like to consider only interactions within 5 A between any

by the way have someone had problems with the pdb2pqr usage with APBS in pymol? I've tried to install pdb2pqr from source as well as via packages then I've add usr/bin/pdb2pqr to the APBs plugin window and when I've started APBS I obtained error like Error: 5 type
