Hi, Sorry if this is basic- I'm a bit of a novice.
I'm running the longitudinal pipeline on patients with three time points. For one of the time points the .long pail surface has included some of the superior sagital sinus as it ascends between the occipital hemispheres. The white matter mask is good, the base image pial surface is good, and the original "cross" image for this time point also doesn't have this artefact. Reading the longitudinal edits on the wiki it seems to advice agains editing the .long brainmask -even though I think it would resolve this situation if this was in a "cross" image/subject? I wondered about editing the brain.finalsurfs.mgz image? but the wiki is quite specific about this only being for cerebellar problems. The occipital lobes are are a region of interest in my study so keen to get accurate surfaces. Could you advise on where to go from here to edit this? I hope the above makes sense and thanks for your help!
