Hi SPMers,
I use SPM5 to create mean image of children and I want to create also the
standard deviation images. With VBM5 I can create these images; function
check sample ...
But The goal of my study it to do progressive calculation. So add one
patient to the first group without do again all the calculation but just use
the mean and standard deviation of the first group.
I think use ImCalc to do this.
But I am not sure if ImCalc do the calculation for all the image or at each
voxel, And also for VBM I am not sure what it does.
In fact, I do calculation with ImCalc and I have very different result that
with VBM5.
Thanks for yours help/advice
Vincent
