Hi Bram, there is not a way to do it with a single command. You could use the aparc+aseg, merge the two hemi labels into one, then run mri_segstats. If you want to stick with pure surface-based analysis, then you'd have to run mri_segstats twice, then just compute a weighted mean of the two waveforms (weighted by the number of vertices in each) doug

Hello FreeSurfer Team,
I've made a New Year's resolution to stop bothering Andrew Hoopes and instead send my questions to the FreeSurfer Mailing List.
I would like to calculate a single average waveform for two surface labels on contralateral hemispheres. In essence, I would like to treat these contralateral labels as a single label.
Is there a way to use freesurfer binaries (e.g., mri_segstats) with, lh.func.mgz, rh.fun.mgz, lh.ROI.label, and rh.ROI.label to write a text file with a single average waveform column?
Thanks! I hope all is well in Boston!
Cheers, Bram
