Dear CCP4ers,
I've created an artificial map in C2 with MAPMAN and made sure that
the axis order and sampling is consistent with SFALL, which I want to
use for calculating structure factors from this map. However, SFALL
(MODE SFCALC MAPIN) fails with the rather obscure error message:
"SFALL: *** You are unable to refine this Spacegroup!! ***" I've
never encountered this error message before - what does this mean and
how can I convince SFALL to do the Fourier transformation?
The articifial map was made by placing single atoms in a C2 cell
including all symmetry equivalent atoms, creating a mask around these
atoms with MAMA and setting space group and axis order in MAPMAN
(axis order ZXY). I used MAPMASK to limit this map to X=0,1, Y=0,0.5,
Z=0,1 as required by SFALL.
Best regards,
Dirk.
