I am trying to use psfgen to generate a psf file for bicarbonate. It creates the files but they are empty. I think the problem is with my topology file but I'm not sure exactly what it is. Any help would be greatly appreciated!
This is the output I get from the TK console and I have attached my topology, pdb, and pgn files
