Table 2.

Tracking parameters used in the experiments. Step and curvature are listed with two commonly used units.

Step (μm)	10	15	20	25	30	35	40	45	50
Step (×voxel size)	1/20	1/13.3	1/10	1/8	1/6.6	1/5.7	1/5	1/4.4	1/4
Curvature (μm)	35	39	44	50	59	73	97	144	287
Curvature (angle in °)*	90	80	70	60	50	40	30	20	10
Cut-off (×10−2)**	0.75	1.125	1.5	1.875	2.25	2.625	3	3.375	3.75
Number of streamlines (×103)	50	100	150	200	250	300	350	400	450	500

^*angle is computed for step size of 50μm.

^**cut-off is the FOD amplitude threshold for stopping the tracks.
