Dear Freesurfers,
I computed the functional activation in a sensory task using freesurfer's fsfast stream. In the cortex surface line like activated regions are present. Their extension is much larger than the extension of the expected regions. Therefore, I suppose that those regions are due to vessels. Is there a possibility in freesurfer to remove them. Ideally there would be something like a volume based mode which does not sxclude the cortex. In this mode the vessels couls be identified and removed. Any help is highly apprexiated.
Respectfully yours
