Hi, I want to calculate the sigmaa-weighted 2mFo-DFc composite omit map, and tried the following 2 scripts:
(1) ./omit hklin ${f}.mtz mapout ${f}.map <<EOF LABI FP=mFo FC=DFC PHI=PHIC RESO 29.50 3.22 SCAL 2.0 -1.0 EOF (2) ./omit hklin ${f}.mtz mapout ${f}.map <<EOF LABI FP=FWT FC=FC PHI=PHIC RESO 29.50 3.22 SCAL 1.0 0.0 EOF The output maps are just different, and I wonder why. I am also more concerned about which one is more appropriate for the sigmaa-weighted 2mFo-DFc composite omit map. (mFo is what I generated from the SIGMAA output) Thanks for any suggestions! Best Regards, Hailiang
