[buster-discuss] Rfree lower than R

[Dirk Reinert]

Hi all,

I am encountering a pretty strange problem at the moment refining a 2.5A 
structure with 14fold ncs (strict ncs, test set assigned in shells): 
using BUSTER-TNT Rfree always drops down below R. This does not happen 
when using CNS or REFMAC and I have not the slightest idea what the 
problem is.

Thanks a lot for any clues

Dirk.
