Dear all,
I am creating a hand-drawn label of the Intraparietal sulcus on fsaverge.
When I register it to an individual brain (mri_label2label), the area is incorrectly registered and comprises adjacent brain structures that I am not interested in analyzing (specially the neighboring sulci).
I know that registration works with my data in general, since other regions (manually drawn on fsaverage, i.e. various pre-motor areas) are correctly registered.
is there any bias or "reduced" accuracy when registering regions of interest located at the parietal cortex?
I am aware that aparc2009 comprises an area called "S_inrapriet_and_P_trans", but I've found that this label is not restricted to the sulcus (in individual segmentations).
Any help would be appreciated!
Bastian
