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.
Me too (more or less).
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.
Not much.
Does anyone
know what type of map this would be in the Fo Fc terminology?
"A mistake".
Actually, the PHWT and PHDELWT are related. AFAIU, somewhere in Refmac
there is something like this:
if DELFWT < 0:
DELFWT = - DELFWT
PHDELWT = 180 + PHWT
else:
PHDELWT = PHWT
