Hi Graeme,

   Unfortunately the Chimera unit cell dialog only makes use of unit 
cell angles, edge lengths and the crystal space group from PDB format 
files.  It may be that our CIF reader also reads those parameters, and 
if it does it should be easy for me to improve the unit cell dialog to 
work with them.  Could you send me a CIF file so I can try with your
