Hi,
I have two related questions. I have two conditions (e.g. C1 and C2)
and I want to generate a map that shows all voxels that can differentiate
C1 from C2 *irrespective* of whether C1>C2 or C1<C2. I think it can be
done easily by:
mris_calc -o sig.nii abs_sig.nii abs
If I am right, then:
1) Can I apply the same command to ces.nii file to have the absolute value
of the effect size (i.e. abs(C1-C2 effect size)) or should I consider other
factors?
2) Do I need to apply the same routine to cesvar?
Thanks
