[ccp4bb]: NCS set up in DM program

[Meng-Chioa Joseph Ho]

Dear All:   I try to do phase extension (from 10 angstrom to 3 angstrom resolution) by applying two 6-fold NCS averaging in my Asymmetry Unit. Both NCS operators are parallel to Y-axis of the unit cell. In term of set up my NCS operator, how should I do it? Type rota polar 6 times to define one of my 6 fold NCS operator ROTA POLAR 0 0 0 ROTA POLAR 90 90 60 ROTA POLAR 90 90 120 ROTA POLAR 90 90 180 ROTA POLAR 90 90 240 ROTA POLAR 90 90 300 ROTA POLAR 90 90 360   or I just need to type ROTA POLAR 0 0 0 ROTA POLAR 90 90 60   For the TRAN Should I type fraction or real coordination number for the TRANS?     And should I do Solvent Flattening and Histogram Mapping too?   Thanks for your help!   Joseph
