Dear Freesurfer experts,

Now I have an annotation file in fsaverage space and a MNI voxel coordinate of one subject. May I ask how could I know if this coordinate is in one parcel of the annotation file? There are many coordinates that I cannot check it one by one in Freeview. In addition, if this is a native image coordinate how could I check whether it is in a parcel then?

An additional question is whether the spaces of all the files in folder "mri" generated by recon-all are native individual space? What do the files 'orig.mgz', norm.mgz'', 'brainmask.mgz', 'brain.mgz' and 'T1.mgz' refer to? They are very similar to each other, with skull-stripped or not. Is there any document on it I could reference?

Looking forward to your kind suggestions,

Many thanks and best regards,

Lizhi
