Hi Daiana
yes, that is to be expected given the nonlinear nature of the cross-subject registration. It shouldn't bias things, although you'll need to give us more details if you want a more definitive answer.

Hi All,
My question is about using mri_label2label. When mapping the labels from one subject to another the number of vertices of each ROI is different. Is that something to be expected?
How much of a difference does a number of vertices of 50 compare to 40 have on measures like thickness, grey matter and surface area?
I would really appreciate some help
Thank you,
