Thank you so much!

Where do I find out how to run the longitudinal stream, please?

Best wishes,

you can also use our longitudinal stream that improves sensitivity and reliability. Run it after you have run the cross-sectional - it will improve your results considerably

Hi Hamied,

I believe you can use mri_segstats (MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://surfer.nmr.mgh.harvard.edu/fswiki/mri_segstats [secure-web.cisco.com]) to generate the stats.

Best,

Yujing

Hello,

I’ve run recon-all on patient T1s acquired at different timepoints after a neurological insult, in FreeSurfer v7.3.2

I want to analyse any change in the volume, surface area and average thickness of specific regions across time in each patient. Can I do this in FreeSurfer?

Many thanks.

Best wishes,

Hamied
