Hi Elaine, OK, that is what I had expected to happen yes - and that NMR ensemble looks to be what I was anticipating. I've attached the PDB chimera created here. I'm no expert on PDB internal formatting but it at least looks to me like there are coordinates, sequence information etc etc. I had thought that I had taken care to make sure whole models were saved (not just sel atoms), but I'll replicate it to make sure. Applying the preset in any event didn't work. Maybe you can spot what's wrong with it? Joe Healey M.Sc. B.Sc.
