Hi Doug, Missed it in the help. Thanks. Cheers, -Morgan Doug Greve wrote: 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 tim

2007-07-05 Thread Morgan Hough
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. Cheers, -M
