Hi there,
I am using the following script to calculate the composive omit map:
./omit hklin ${f}.mtz mapout ${f}.map <<EOF
LABI FP=FP FC=Fcalc.FC PHI=PHIC
RESO 29.50 3.22
SCAL 2.0 -1.0
EOF
Here FP is the experimental Fo, Fcal.FC/PHIC are calculated structure
factor/phase from the model.
My output map seems quite biased toward the model, because if I remove a
partial model, the denisty at the removed region almost completely
dissappears.
I am wondering whether I did something in my script, or the omit map is
supposed to behave like that since it is not sigmaa weighted. Furthermore,
I am wondering whether the 2Fo-Fc composive omit or the sigmaa weighted
2mFo-DFc map has more model bias.
Thanks for any help!
Best Regards, Hailiang
