Irene,

There are two parcellation schemes that freesurfer produces. The ? h.aparc.annot file contains 35 labels, while ?h.aparc.a2005.annot contains 78 labels. If you specify ... -a aparc.a2005s.annot in the mris_anantomical_stats command, you will get the 78 labels.

The two schemes are described in the papers in the cortical parcellation section of the wiki:

?h.aparc.a2005s.annot - Automatically Parcellating the Human Cerebral Cortex

Hi all, I'm trying the new version of FS for a study on multiple sclerosis that our group in Padova (Italy) is doing. When I give the command "mris_anatomical_stats -b -a aparc.annot etc..." to obtain the list of cortices, I obtain about 30 cortices, while in the last version of FS I could obtain about 80 cortices. So, can I obtain 80 cortices also with the new version of FS? How can I do it? Thanks
