I can run Dock Prep on a PDB file containing zinc (1zip) without the problem you're getting. Can you tell me what PDB you're using, and what version of Chimera? --Eric Eric Pettersen UCSF Computer Graphics Lab pett@cgl.ucsf.edu http://www.cgl.ucsf.edu On Oct 8, 2007, at 10:54 AM, zzj wrote:

Hi there, I am preparing dock6 files in Chimera using the Dockprep option. The Zn and K ions in the PDB files are giving me problems at the point of adding hydrogen. Everthing works fine if I remove these ion atoms. Here is the Chimera Error message: AttributeError: addHinfoDialog instance has no attribute "cancerlCB". I can select and highlight these ions without problem. I tried to give different names for the ions. Nothing worked. Any suggestion is highly appreciated! -Joe _______________________________________________ Chimera-users mailing list Chimera-users@cgl.ucsf.edu http://www.cgl.ucsf.edu/mailman/listinfo/chimera-users
