Drawing voxels

Hello AFNI folk,
I was wondering if one can create a 3D picture using an anatomical as background and add to it an ROI and individual single voxels at specific coordinates in various colors. Is there a way to have the program read in the coordinates of the specific points and of the ROI? I don’t know if there is a simple way.
Thanks for your help and attention.

Are you thinking of the Draw Dataset plugin? You can start with an anatomical dataset and draw with various intensity values that get displayed in different colors.
