You will need a registration between the space where the ROIs are and the anatomical. We usually do this with bbregister, but you will need to identify a volume that is in the ROI space that has anatomical contrast so that the registration can be done (ie, dont use the ROI mask for registration). Then you can run mri_vol2surf specifying the ROI.nii.gz as the mov volume and the registration from bbregister. After that you should just be able load it as an overlay on the patch.
