Hi Octavian
it's hard to say. I would think you could get a bunch of it automatically by looking for places that are significantly different between the two timpoints, but that will depend on how well they register. You can certainly do it manually in freeview.

Dear All, I have 2 coregistered MR volume (pre and postresective MRI) sets for several epilepsy patients. I need to extract the resection volume (VOI= pre - postresection volume) as a set of voxel coordinates. Can I do this in freesurfer? Ideally I would avoid manual delineation slice by slice as in MRImicro and if possible I would do it automatically by thresholding, for example. If not, manual is fine if it can be done in FS. Please advise. Thank you, Octavian.
