There is nothing in SPM that will make segmenting lesions easy as it assumes
that brains consist only of GM and WM, with a bit of CSF around it. Dealing
with lesions is another thing on my to-do list.
You may want to try the EMS software, although I think it probably still needs
SPM99 in order to work.
