Dear experts,

I have created a vmPFC mask (I have included brodmann areas 10, 11, 25 and 32) using the WFU_PickAtlas and ran a ROI analysis on our data.
The problem is that the mask not only includes the medial part but also the lateral and I need to include only the medial parts... Is there anyway I could create a mask that only includes the medial parts of the chosen brodmann areas?

Thanks,
Claire

Hi Claire,
  The best recommendation I can make is to:

Use Advanced ROI feature to intersect with midline box:

 

Advanced

Add BA regions 10, 11, 25, 32

Select all regions in Working Region box Press Union

 

Select Shapes from ATLAS Regions

Select Box

Go to MNI coordinate: 
0 -20 0 (using coordinates at bottom of gui) Set box size to :  20 90 90 
(x coordinate determines midline extent) Generate Shape Select all
regions in Working Region and press Intersect Commit

Hope this helps,

Ben
