Hello Freesurfer users/experts,

I am working with Freesurfer 7.4.1 on a MacStudio (macOS 15.2) and I would like to ask your opinion about the following.

Basically, we had an anxiety treatment study and I would like to analyze one subject who has 5-time points (0, 3, 6, 9, 12) with a longitudinal pipeline, two-stage model.
Is it possible to run this on one person only and see the changes between these time points?

I have never done this before on one subject so I am not sure what the best approach would be to look at the changes.
After running the longitudinal preprocessing (base, long), should I generate the tables of freesurfer parcellation/segmentation stats data
(aparcstats2table, asegstats2table)?
Or can I just follow the two stage model steps? Maybe glm only works on a group of subjects.
MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://surfer.nmr.mgh.harvard.edu/fswiki/LongitudinalTwoStageModel

(We have 9 more subjects - 10 in total - so I was hoping to visualize the pattern of changes one by one, in each subject, since these patients showed different changes in anxiety based on self-reported
questionnaires)

Sincerely,
Isa Rosselini
