I have a 3D EPI functional map including different activated brain regions. I would like to define the ROI based on the activation map for each brain nuclus.
I followed the Methoda 2 in the PDF handout. afni11_roi. Now, I got the mask including all the activated brain nuclei. How can I separate them into individual nuclei mask. Is there a ROI deselect tool in AFNI?
I checked the Draw dataset, in the Mode option there is Flood->zero. It didn't seem to work in my case.
Thank you
