Hi Charlotte,

know, it isn't a problem. It can be helpful to create your own average subject that will more accurately reflect the geometry of the coordinate system in which you are processing your results, but in general they won't be very different from fsaverage.

Dear Freesurfer experts, I would like to know if it is necessary to have exactly the same number of subjects in my fsaverage and in my qdec.table.dat? If it is a problem how can I eliminate the subjects I don't study from the fsaverage? Thanks for all, Charlotte
