If FLAG==0 inactivate, else activate 4 - in/activate fibers with at least VALUE points (or less than VALUE if PARAM&1) If FLAG==0 inactivate, else activate 5 - set/clear param for tracks where ?? 7 - save active objects as new data set 8 - set OBJFLAG to ROIVALUE 9 - set OBJMASK to ROIVALUE Note: track param bit 1 means track is active ROIVALUE - index value in ROI mask 0 - all voxels
