[caret-users] displaying several ROIs simultaneously

[John Harwell]

Binyam,

You will need to combine all of your ROIs into a single image.  For a  
paint volume, there are no controls for turning the individual paints  
(ROIs) on and off.  However, if you load the image as a probabilistic  
atlas volume, you can turn the ROIs on and off using the Display  
Control's Probabilistic Atlas - Volume Area page.
