Hi Martin:
I processed a patient (with two MRIs in different dates) using the instructions in the web page that you told me, but I didn't understand very well the results that I got...
Which values I got in aseg.stats with:
i) recon-all -base <templateid> -tp <tp1id> -tp <tp2id> -all
ii) recon-all -long <tp1id> <templateid> -all
iii) recon-all -long <tp2id> <templateid> -all
Sincerely,
Gonzalo Rojas Costa

Hi Gonzalo,
you should run your data with the longitudinal stream (if you use fs 5.0 update mri_robust_template and recon-all first), see infos on : http://surfer.nmr.mgh.harvard.edu/fswiki/LongitudinalProcessing
After processing, you can compare the volume measures in the /stats/aseg.stats files from the longitudinal directories. You can also map both the asegs from the long dirs to base and compute dice coefficients on specific labels, or you can compare surface measures etc. For all this you should be familiar with the cross sectional stream in freesurfer.
Best, Martin
