Hi Emmanuel,

I think this should be identical to the cross sectional situation, you map that cluster (defined on FSAVERAGE) to each subject_time_point and then use mri_segstats to get stats on that region. Probably others can help you with what tools exactly you need for this (or probably this can be found on the wiki or archive).

Best, Martin

    External Email - Use Caution        

Dear FreeSurfer experts,

Am analysing longitudinal structural data with the LME model algorithm. I will like to map the significant cluster after analysing the data to all subjects at all time points, extract the values for all and perform further statistical analyses. Please how do I go about extracting the cluster value from all subjects at all time points? Any help will be appreciated.

Kind regards Emmanuel _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
