Dear All,

I am trying to refine a cryoEM structure containing a simple glucose disaccharide using CCPEM + CCP4-8.0

but I get the following error from Refmac Servalcat :

ERROR : atom :O1   BGC                 1  Z4_  is absent in the library
ATTENTION: atom:O1   BGC                 2  Z5_  is missing in the structure

and interestingly, the Coot version coming with CCPEM (0.9.8.5) is also not able to refine my sugar...

However, If I use CCPEM with the older CCP4-7.1, the refinement works fine.

Any idea ?

With many thanks,

Gia
