[caret-users] displaying several ROIs simultaneously

[Donna Dierker]

Binyam,

Assuming you're more interested in selective *surface* paint control, 
and not volume control (as suggested by your mapping ROI volume to 
paint), then you can select certain paint names to display, using the 
D/C paint names dialog (see attached capture).

As John says, you'll need to combine the images in a single volume, to 
get them in a single paint column for this to work.
