Hi Faisil,

Looking at your table, I think your data can go to even higher resolution than 
you report.
Did you setup your data collection for higher resolution?

Cheers,

Scott

Hi Faisal,

A lower R-free than R in the highest bin is not a big problem. The test set in 
you highest resolution bin may be quite small which makes the values not so 
reliable. Phenix uses different bins from what Refmac uses so you cannot 
compare the values. If you performed your final refinement with Refmac, you 
should also take the values from Refmac for your 'Table 1'.
A pet peeve of mine: please report the bond length and angle rmsZ next to (or 
instead of) the rmsd in Table 1. The values are in your Refmac log file.

Cheers,
Robbie

Hi everbody,

I have one question with regards to the Bin R and Rfree values. My overall R 
and Rfree values for (resolution1.4 angstrom) is 15% and 19% respectively.  
But, the values in bin as shown in PDB header after the refinement from the 
REFMAC are 15.7% for R and 14.5% for Rfree. In this R is more than Rfree 
although overall values are fine. Apart from this, when i am generating table 1 
by Phenix, the output is giving the bin values as 16% and 18% for R and Rfree 
respectively.
Can anybody suggest what need to be done?
