Tibor,
We are working to put some exvivo wm segmentation methods into the next
FreeSurfer release although I'm not sure where that stands. We do process
our exvivo scans with FreeSurfer but we use scripts that use different
parameters than recon-all since the contrast is different and as you said
there is no skull. Our scripts are specific to our scan protocol. What did
you collect and on what scanner?

Dear Users,
Is there a way to process fixated brain (after autopsy) with Freesurfer?
I have read somewhere that I should just "invert" the image, but what does
it mean? And would it not increase the noise and the signal from the CSF?
Of course, the brain is without any skull, pia and dura mater. Does it cause
no problem for Freesurfer?
Thanks,
