External Email - Use Caution 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://secure-web.cisco.com/1DvoR9gsljZsd_tn6iXlHFCEa7oldorHsKL8rE7nOuo8r9Z...

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
