[Freesurfer] About the average subject

Hello all

Hello all

We are planning to perform a cross-sectional study involving two population of subjects. I think we have to choice one among two possibilities :

1-Make a single average subject for both populations and resample all the subject to this average for the statistical analysis.

2-Make two average subjects, one for each population.

In the last case we are not sure what is the right posterior processing in order to get the most accurate results from the final statistical parametric map.

Any help is welcome

In advance thank you
