edits should be made to the cross-sectional subjects and the base subjects. edits do not need to be made to the longitudinal runs, as they will be transferred from the cross-sectional subject run. the base subject does not get edits transferred from the composing set of cross-sectional subjects because each of those runs will be slightly different, and edits to one time-point may not apply to another time-point.

Bumping this back up to the list. Could someone please address?
To be more concise, during longitudinal processing, where are wm/gm edits made? On the cross-sectional runs, to the base, or on the .long. runs themselves? Thanks.

Subject: Longitudinal processing clarification
(Questions for all, but maybe more directed towards Martin)
I have some questions about manual edits in regard to the longitudinal stream. Based on the current info on the wiki page, it appears that no edits are pushed forward from the cross-sectional (initial) runs of the subject data, as any information on the *.long.* runs come from the template. However, I've noticed that WM edits and surfs from the template are used for the *.long.* processing. In essence, my question is when/where should manual edits (i.e., control points, WM, pial edits) occur when conducting longitudinal processing in 4.5? It seems I remember that in 4.3 edits in the cross-sectional work would be pushed forward to the *.long.* images, but such is not the case anymore (?). Are edits to occur in the template (i.e., 'base') now, or in the *.long.* runs? Thanks.
