Dear all,
I am refining a low resolution structure (3.0A) in refmac. The problem
is that no matter which value I choose for matrix weight the RMSD for
bonds stays higher than 0.3A (yes, I didn't mistype it, it is really
0.3A). I have tried matrix weight as low as 0.01 and also AUTO.
Since there is two subunits in the assymetric unit I am refining using
NCS. I also tried turning it off but the problem persists. The
coordinate file I entered to refmac came from CNS were I had no problem
with geometry. Since refmac has some advantages (like TLS refinement) I
always try to change to refmac at the end of the refinement.
Is there something I am missing? Thanks in advance for all kind of
suggestions,
Mario Sanches
