Hi Matt, We can't really tell what is going on without that file. Is it proprietary? You could send it to just me and I would keep it amongst the developers here. However, by googling I see there is an ice(VI) CIF available from this page, <http://rruff.geo.arizona.edu/AMS/result.php?mineral=Ice> and I was able to open it in Chimera, but only three dots appear and I get the following errors in the Reply Log. If that is the same file you used and the same result, let us know. MMLIB:WARNING] GetSpaceGroup('P 42/n m c') not found [MMLIB:WARNING] monomer description not found in zipfile for 'GLOBAL' [MMLIB:WARNING] monomer description not found for 'global' [MMLIB:WARNING] monomer description not found in zipfile for 'GLOBAL' [MMLIB:WARNING] monomer description not found for 'global' [MMLIB:WARNING] read_atoms: no geom_bond section found [MMLIB:WARNING] read_atoms: no geom_angle section found [MMLIB:WARNING] monomer description not found in zipfile for 'GLOBAL' [MMLIB:WARNING] monomer description not found for 'global' AMS_DATA.cif opened The CIF reader was developed mainly for mmCIF from the PDB and does not cover the universe of CIF possibilities. It may be a current limitation as opposed to a bug, but we would need to know which file you used. Besides sending email to chimera-users, another approach is to use "Help... Report a Bug" in the Chimera menu and include a description of steps needed to reproduce the problem, attach any file needed to reproduce the problem, and include your email address if you wish feedback.

I am looking for the crystal structures of "normal" ice (Ih), ice(VI), and ice(VII). I have found the .cif file for ice(VI), but I can't seem to get it to load properly into Chimera. I am really only familiar with using pdb's in Chimera. These would be used in a presentation given this coming weekend at the National School for Neutron and X-ray Scattering. Any help in this would be greatly appreciated
