Hi everyone!
Normalize: 3dcalc -gscale -datum float -prefix func_normalized -a func_+orig -b mean+orig -expr "a/b*100"
The normalize I mean is to let the functional data to divide the mean value of themselves.
I want to know if it is necessary to do it so that every subject are at the same level before I do the 3dDeconvolve.
Thanks very much!
