Try the deformations utility. It's a bit tricky to use (because I made
it flexible rather than simple), but (I think) you'll need to set up a
job with the following structure:
Deformations
. Composition
. . Inverse
. . . Imported sn.mat
. . . . Parameter File: select the sn.mat file
. . . . Voxel sizes: NaN NaN NaN
. . . . Bounding box: ones(2,3)*NaN
. . Identity
. . . Image to base Id on: an original PET image
. Save as: leave empty
. Apply to: select the spatially normalised data
. Interpolation: Up to you
Best regards,
