hi FS users;
have two questions which i am having issue across ss and pial/wm/orig surf boundaries
1- it has happened that sometimes the sagittal view of individual was flipped from left to right. but the pial/wm boundaries look good. was wondering why this happened only for countable ppl? i tried to look up in forum for anyone with similar issue but no clue yet...has anyone come across this issue and if yes, how to flip back the orientation in sagittal view
2- how much ss issue should be considered. ss issue= skull pieces left behind, or large GM cut. the reason i m asking is because sometimes there would be a huge piece of skull remaining but that individual would have perfect visual alignment of boundaries and nice inflated surface. sometimes they have mediocre skull remaining or GM cut, and that would make pial/wm boundaries go wrong and inflation is with holes and droplets. my question is how much of skull stripping errors( pieces of skull remaining, gm/wm removed beyond limit or orientation flipped) matters to segmentation, inflation and further analysis.
any help would be appreciated
thanks kk
