HI,I am a beginer in crystallography. I have carried out molecular replacement in 'phenix' and now want to refine the structure in ccp4. Could anyone tell me what the proper Rfree_flag value to put in while using Refmac5(ccp4). I have used 1 and output seems to be fine but I want am not sure if am going in the right direction.
Regards, Madhu
