I see. Getting FS working is going to be a case-by-case thing then. For holes extending into the ventricles you will probably need to fill the hole in the wm.mgz to make the topology closer to what we expect it to be. For the gliomas it depends on where they are cheers Bruce On Tue, 1 Jan 2019, Michael Sughrue wrote:

In some cases this is a hole in the cortex extending to the ventricle...in others it 8s a low grade glioma which substantially enlarges ....and distorts the cortex

yes, we have done this a number of times but of course it depends a lot on the details of the abnormality so it is hard to give generic advice cheers Bruce On Fri, 28 Dec 2018, Michael Sughrue wrote: > > External Email - Use Caution > > Has anyone had success extracting surfaces of brains with obviously abnormal > surfaces....post-surgical or very distorted cortices from tumor etc....even if the extraction is > imperfect, is it possible to do with freesurfer and get something imperfect but useable. > ....typically this gets hung up at the fix tesselation step..... > if this isnt possible presently, any suggestions about how to create modify the source code to > create such a tool? > > On Fri, Dec 28, 2018 at 8:49 PM Matthieu Vanhoutte <matthieuvanhoutte@gmail.com> wrote: > External Email - Use Caution > > Dear Freesurfer’s experts, > > I used mri_coreg command to coregister PET image onto T1 volume.
