Dear SPM users, I am attempting to create a mask for ventral ACC which encompasses BA 25 and more ventral components of the anterior cingulate. I have been given the following information to replicate in WFU Pickatlas: "creating a region that was 5496mm3 (86 voxels) in volume with center at MNI coordinates of x=0 mm, =36 mm, z=4 mm. I am not familiar with how to do this in WFU Pickatlas. Can someone please advise me on how to create this to ensure I have the 86 voxels included. Many thanks rebecca ---------------------------------------------------------------------------- The information contained in this message may be privileged and confidential.
