Charmm atom type
WebI noticed that you have 19 Atoms in topology file (psf) for the first residue, but in the PDB file you have 18 atoms. There should be the same number, are they both created in … WebSep 18, 2024 · MissingParameter: Could not find atom type for CH1E. I think it relates to my psf file (attached) as this has this contains this atom type and the function works with another psf file I have for the same protein but in explicit solvent which doesn't contain this atom type. Any help on how to fix this would much appreciated. Thanks Sarah
