Hi Eleanor,
I hate to disagree with you, even partially, but it depends on whether or not
you're doing phase combination with external phases. In the usual case with
just model information, SIGMAA doesn't take the absolute value of 2mFo-DFc so
it can be positive or negative and goes with the o
Actually I think it needs the labels FWT PHWT
I may be wrong but like REFMAC I think it outputs a ositive FWT and PHWT
is either equal to PHIC or to PHHIC+180, depending on the sign og
FWT = (2m|Fo| - D|Fc|)

Dear Hailiang,
the man-page of sigmaa claims
FWT (2m|Fo| - D|Fc|) exp(i AlphaCalc)
Analogous to 2Fo-Fc map, FFT input: F1=FWT PHI=PHIC
^^
so I would leave out WCMB.

Hi there:
When I generate the mtz file by SIGMAA, and want to view the 2mFo-DFc map
in coot, should I choose "FWT PHIC WCMB" combination or just "FWT PHIC"? I
think the later is more reasonable and I did see somebody the former as
well. Didn't see explicit instruction in SIGMAA document, and I app
