Hi Tim, I thought that I had the problem figured out. Since the PDB was edited from a protein/DNA complex the ATOM numbering was not starting with 1, but rather started with ~1000. I thought this might be throwing the import off. I renumbered the PDB ATOM field from 1 - X using Moleman and it didn't fix the problem like I thought. Bummer? Other than that I can't see any thing wrong wtih the PDB that I am using. I did send it to you, did you get it? -J On Feb 27, 2007, at 10:47 AM, Tim Stevens wrote: >> I have an edited PDB file that I am trying to load into CCPNMR.
