i do not yet have any anatomically defined area labels, and i have a functional comparison that activates the area i want as my ROI, but some other areas as well. is it possible to manually edit the functionally thresholded mask to have only the ROI i want, by somehow deleting the undesired voxels (or changing their value to 0)?

let me know. thanks, t
