RE: Lesion drawing with Damasio 1989 template
Are these modern CT scans or is this an archival study? 

Once upon a time, CT scans were acquired with irregularly spaced slices (more near the brain stem, fewer slices for the cortex) and with substantial gantry tilt. The wide spacing between slices typically render these slices a poor choice for normalization. You may want to see if you can take a popular slice and angulate the volume to match the Damasio slides. My legacy MRIcro software has a "free rotate" button that helps, but you could also do this with SPM:

For modern CT scans, these images typically have good spatial accuracy in all planes and can be warped to standard space using my clinical toolbox for SPM. I would suggest using a modern MNI-oriented atlas rather than the legacy Damasio atlas, as this will aid translation to studies using other modalities.
