Hello AFNI Gurus!
I have extracted Hippocampal masks from participants' Freesurfer segmentations. I want to subdivide this ROI into thirds along the anterior-posterior axis (y-axis?). E.g., if a certain participant's hippocampus goes from slice 90 to slice 120 , I want the first ROI to go from slices 90-103, the second ROI to go from 104-117 and so on. I am using 3dAutobox to get the extent of the ROI, but I can't figure out to the command to divide the ROIs based on these slice numbers. Is there a way to do this?
Thank you,
Mrinmayi
