I am trying to run BFEE on my protein-ligand complex in a ionized water environment. I have all the NAMD files from my simulation; however, when I go to run BFEE with the files I get "the domain error: argument not in valid range". Does anyone know how to possibly fix this or has experience using VMD BFEE? I am using the restart files for .coor, .xsc, and .vel.
Below is the protein-ligand complex. I recognize that my ligand is just a small chain of amino acids.
