Hi Linda,

When using something like the FreeSurfer parcellation,
this is not a clustering step but an ROI step. It should
be enough to run 3dROIstats (3dmaskave, or whatever) on
such datasets. For example, from the same directory:

set hem = lh
3dVol2Surf  -spec          ../SurfData/SUMA/std.DemoSubj_${hem}.spec   \
            -surf_A        std.${hem}.smoothwm.asc                     \
            -surf_B        std.${hem}.pial.asc                         \
            -sv            DemoSubj_SurfVol_Alnd_Exp+orig      \
            -grid_parent   DemoSubj_EccExpavir.DEL+orig        \
            -map_func      ave                                 \
            -f_steps       10                                  \
            -f_index       nodes                               \
            -oob_value     0                                       \
            -out_niml      r.v2s.${hem}.DEL.niml.dset

3dROIstats -minmax -mask ../SurfData/SUMA/std.lh.aparc.a2005s.annot.niml.dset r.v2s.lh.DEL.niml.dset

How does that seem?
