same issue already discussed some time ago, have a look at this topic: http://www.mail-archive.com/coot@jiscmail.ac.uk/msg01180.html
it would be nice if, when saving PDB files, coot would completely discard the CONECT lines.

The problem is in the connect lines at the bottom of the file - if you remove them then pymol reads the file just fine. You could say that this is a pymol read problem, But I'm going to suggest that this is a coot write problem. These connect lines must mean something and whatever they mean it's not the same after you rotate the coordinates. So, maybe coot has to rewrite the connect files or leave them out? Heidi
