Dear All, I have 3 minor questions/problem and would be grateful for some help. 1a. Providing the XDS_ASCII.HKL to phenix tableI works perfect, however there are no values written for CC1/2. The same file in phenix.merging_statistics I get the CC1/2. Am I missing something? 1b. The only value phenix tablel one takes from INTEGRATE.LP (i guess CORRECT.LP will work too) is the wavelength - true? 2. I see some negative density around the seleniums in my selenomethionine labeled protein. I guess this is due to radiation damage. Is the accepted standard to do occupancy refinement for just the sidechain, or just parts of the sidechain, the whole residue or just leave it like it is. For the side chain refinement.refine.occupancies { constrained_group { selection = resname MSE ( name CB or name CG or name SE or name CE or name HB2 or name HB3 or name HG2 or name HG3 or name HE1 or name HE2 or name HE3 } } should work or? I am using version dev-1334 on ubuntu. Best regards Georg.
