How to perform a brain CT perfusion coregistration with anatomic atlas?

Hi all,
starting from the CT perfusion DICOM files I obtained, using 3DSlicer, the nifti penumbra VOI.
Now I want to check which anatomical areas are affected based on the AAL atlas (possibly using MRIcron, but other software are fine). I am stuck in the coregistration phase; I have already tried SPM without satisfactory results. How can I adapt a VOI extracted from a CT to an atlas?

Thanks for the advice, I am new to neuroimaging analysis, so any suggestions are welcome.

See the post here for how to do this in AFNI. Apply the computed transformation to move the region with 3dAllineate -1Dmatrix_apply. For ROIs, also use the “-final NN” option for nearest neighbor interpolation.

The Clinical Toolbox for SPM was designed for this purpose. It includes a tutorial with sample images to demonstrate how to use it. It is described here.
