Surface ROI ˆ Volume ROI
by Rick Reynolds
¥Output file OccROIs.1D.dset is of the form:
H1241
H1251
H---
H288219
H---
¥OccROIs.1D.dset can be transformed into a volume ROI with 3dSurf2Vol
¥Execute: source run_3dSurf2Vol
H3dSurf2Vol  -spec../SurfData/SUMA/DemoSubj_lh.spec   \
            -surf_A        lh.smoothwm.asc                     \
            -surf_B        lh.pial.asc                         \
            -sv            DemoSubj_SurfVol_Alnd_Exp+orig      \
            -grid_parent   DemoSubj_SurfVol_Alnd_Exp+orig      \
            -map_func      max                                 \
            -f_steps       10                                  \
            -f_p1_mm -0.5  -f_pn_fr 0.5                        \
            -sdata_1D      OccROIs.1D.dset                    \
            -prefix        OccROIs
H-grid_parent specifies the output volumeÕs geometric properties
H-f_p1_mm, -f_pn_fr: Specify extensions on node pair segment, either in mm or fractions of segment length (both used simultaneously here for illustration)
H-sdata_1D: Specify surface data file
