Dear FS experts
We divided the superior temporal sulcus derived from the aparc.a2009s.annot into parcellations of 300mm2 (using mris_divide_parcellation) and computed the mean cortical thickness within each parcellation. So far so good.
But we noticed that each parcellation has a unique surface area that deviates largely from 300mm2 (96-480mm2).
We defined the parcells on the fsaverage template and transformed them back into the native space of each individual. Therefore, we expected some variation in the surface area, but not such large differences.
How to explain it?
Thanks in advance Regards Jürgen
