I want to use this mask to exclude everything below the AC-PC line from statistical analysis. I can't find a way to apply the mask. As I specify and estimate a model, I am not asked if I want to apply the mask. Please describe the steps necessary to use a mask in SPM99 for fMRI data. Jerry Allison, Ph.D. Medical College of Georgia
