Hi ccp4 experts,

I have collected diffraction images to 0.96 Angstrom resolution to the edge of the detector. One data set give me the full completeness and  
below i have pasted my statistic values got from XDS.

I have cut off data at 1.12 A  which seems to be quite nice regarding all necessary parameter to consider.

But the problem is the Rfree is 0.176 and Rwork is 0.151 but the maps look very good.   Even If I cut off  the data to 1.15 Angstrom the R factors not improved. The space group of my complex is P21212.

I used anisotropic Bfactors, add Hydrogen on and also used TLS  but unfortunately i can not reduce able to reduce R factor in a good way.

so, could you people kindly give me some suggestion how can i improve my data quality.
