Hello Freesurfer experts,

I would like to extract time series of pre-processed data from each vortex of ROIs in a annotation file, may I ask how could I achieve this?  I tried 'mri_segstats' which only generated the mean time series of each ROI. I also tried Matlab, but 'read_surf' doesn't seem to work in import brain functional data (e.g., fmcpr.up.sm5.fsaverage.lh.nii.gz). If there is a way to import functional data into Matlab? And how could I use the information in the annotation file to get time series of each vortex in a ROI? Thank you very much.

Best regards,

Lizhi
