Hi Doug,
Missed it in the help. Thanks.

It should be in the help (reprinted below). Smaller delta is better but takes longer. With big functional voxels, I would not agonize too much over making delta real small as you'll just hit the same voxel multiple times. .25 is probably sufficient.

--projfrac-avg min max delta --projdist-avg min max delta
Same idea as --projfrac and --projdist, but sample at each of the points between min and max at a spacing of delta. The samplesare then averaged together. The idea here is to average along the normal.

Hi there,
Hopefully a quick question. I was wondering what the del represents in the mri_vol2surf option --projfrac-avg?
--projfrac-avg min max del
If I use 0 and 1 for min and max, what should del be to average across all the voxels between the two surfaces? Thanks in advance.
