Hi all, I am refining a protein structure with phenix and COOT, and COOT worked fine for three runs. The pdb file is composed of two protein chains, two ligand chains, and a water chain. Suddenly at the last run the pdb file opened by COOT only has chain A but the mtz file still displays all the chains, while the same file opened by Pymol contains all the chains. Does anyone know how to solve the problem? I am using Mac OS 10.6.8 system, and the COOT version is 0.7. I have tried to uninstall and install it several times with two installation files (one from the CCP4 website, the other from a link on phenix documentation), and it does not help.
Thanks! Jane
