Dear Eleaonor and CCP4ers,
I always wondered, why there are phase columns PHWT, PHDELWT (Refmac)
or PH2FOFCWT, PHFOFCWT (phenix.refine) in addition to the PHIC column
of the atomic model. In absence of other phase information, the phase
should come from the atomic model, only.
Best regards,
Dirk.

It would be a cock-up map. Unless there is exptl phasing
PHDELWT = PHIC when mFo-DFc is positive, and mFo-DFc is negative it
equals PHIC + 180

Dear cootbb,
When building into density I use a map generated from the FWT
amplitudes column and PHWT phases columns which I think is my 2Fo-
Fc, and a second map generated from DELFWT and PHDELWT which I
think is my Fo-Fc. This keeps me happy and in known territory.
However today someone in the lab asked what it means to generate a
map using FWT and PHDELWT. Does anyone know what type of map this
would be in the Fo Fc terminology?
Thanks,
Simon
