Hi Sarah,

What are the problematic atoms that AutoPSF is complaining about? Sometimes AutoPSF does a poor job of assigning chain values, especially if your initial PDB file has residue names that can't be found in the topology file. Where did you get the original PDB file?

In the file there was only 3 atom of the residue. I tried deleting the information of the 3 atoms in the *.psf file to rewrite the required data. It didn't work.
