[Marsbar-users] combining ROIs

[Carolyn L. F. <cl...@ma...>]

Hello.

We've created six ROIs within the pre-frontal cortex (which combined comprise the PFC in its entirety) and have looked individually at the extracted data. Now we're interested in the PFC as a whole. I'm assuming the appropriate step is to combine my six ROIs and run a new extraction, yes? Would averaging or summing the data from the six individual ROIs tell me anything meaningful about this region?
