Hi afni experts,
I have a mask dataset that is comprised of 9 different values (1 thru 9) that represent different regions of interest. Is there an easy way, possibly using 3dcalc, that allows to make various new mask datasets of some of the select values? For example, lets say value 7 is the left prefrontal cortex and value 8 corresponds to the right side. How can I create a new binary mask dataset that combines these two values into one large region (so the mask now is a bilateral prefrontal cortex mask)?
Thanks for your help!
