Creating a vmPFC mask with WFU_PickAtlas
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:
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
