Hello Rebecca,
Unfortunately without more information there are numerous ways to
create an ROI with the information below...and most will not give the
requested volume. Additionally, as the default images produced from the
PA are in 2mm isotropic, 86 voxels would produce 688mm3. I would
suspect the "target" ROI is not in the native PickAtlas space.
If you receive more information on the creation of the ROI, please let
me know and I'll be glad to lead you through crating it.

Subject: [SPM] creating mask using WFU Pickatlas
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
