Thanks Doug. I am now able to get average time series from cortical ROIs. I used mri_segstats --annot fsaverage lh aparc --i sess01/bold/001/fmcpr.up.sm5.fsaverage.lh.nii.gz --avgwf test1.txt
That's right, but I would use the unsmoothed data since smoothing will cause activity to spill-over between regions.
How would I get time series of the sub-cortical ROIs (fmcpr.up.sm5.mni305.2mm.nii.gz)?
I tried doing
mri_segstats --seg fsaverage/mri/aseg.mgz --ctab $FREESURFER_HOME/FreeSurferColorLUT.txt --avgwf test2.txt but it gave me dimension mismatch error. I'd appreciate if you'd direct me on how to get average time series values from subcortical regions.
Use fsaverage/mri.2mm/aseg.mgz

Yes, mri_segstats. Run it with --help. See esp example 6

Hi FS Users,
I've preprocessed resting state fmri data using preproc-sess as shown in FSFAST functional connectivity walk through manual. I know I can extract mean time series of a seed region using fcseed-sess. I am trying to find a command to extract mean time series from all Desikan (or Destriuex) atlas ROIs. Looks like mri_segstats is the command to get the time-series of all the ROIs at once in a .txt or .dat files but I am not sure how exactly to do it.

Thanks for help.


Cheers,
