Hi all,
          I have a little problem... R and R-free  from phenix.refine are  22.9 and 30.6 respectively.... when i validated in the rcsb server... sfcheck gave me a R and Rfree of 30.8 and 37.8. I am aware that sfcheck never reproduces the result. but i am worried that the difference is quite large... indeed i have used TLS NCS and bulk solvent correction... 

Did i do anything wrong... please help me

Thanks for your help

regards
John
