 +  * 01000 - ignore thresholds (default: use threshold if active)
 +  * 02000 - calculate cycle-to-cycle variations (not with 010000 option)
 +  * 04000 - binary mask; values above threshold are ON (default if no REFIMAGE)
 +  * 010000 - threshhold curves; calculate stats for 10 different threshold values (see THRESHOLD note)
 +  * 020000 - include negative values
 +  * 040000 - show only non-zero values, not total voxel counts
 +  * 1000000 - use threshold, even if THRESH is 0 (this is default if THRESH is non-zero)
 +THRESHOLD: THRESH arg is the lowest threshold and stepsize.
 +If OFFROI is non-zero this will generate ROC curves.
 +If IGNOREROI is non-zero, REFIMAGE voxels with that value are ignored.
 +If ONROI is non-zero, only REFIMAGE voxels with that value are included.
