Though one workaround might be to subdivide a label many, many times using mris_divide_parcellation, I was wondering if it is possible to obtain a per-vertex (or even per-face) fMRI waveform for a label. In other words, rather than compute the average waveform
across all vertices, as with mri_segstats --label subject semi /path/to/label --avgwf avgwave.txt, which yields a single value that averages across, say, 5000 vertices, I would like to obtain each of the 5000 waveforms averaged over. I assume this would be
more comparable to the scale of analysis used by those looking at voxel populations (e.g., as in MVPA).
