I would change the step size to be 1/4 the voxel dimensions. Keep the other
stuff the same.

Subject: [FSL] probtrackx options for monkey brains
Can anyone recommend options in probtrackx that are best suited for monkey
brains (1mm resolution)?
Specifically, what should the step length be (and the number of steps) ?
The website mentions step length should be changed depending on "voxel size
or brain size". Any other options we should consider changing from
default (number of samples, curvature threshold) ?
