1. A non-transitory computer readable medium for performing a method by running a software program on a computer, the computer readable medium comprising instructions for a computer to transform magnetic resonance imaging data into a visualization of neural pathways in the brain for tractography by diffusion tensor imaging or fiber tracking, the instructions comprising: obtaining a magnetic resonance imaging data representing a first plurality of brain fiber tracts; accessing a plurality of variable fields within the software, the variable fields including a fractional anisotrophy ratio field and a fiber length field; setting the fractional anisotropy ratio field to a constant of about 0.26; setting the fiber length field to a constant of about 60 mm; determining positional coordinates and orientations of the first plurality of brain fiber tracts by applying the constants set for the fractional antisotrophy ratio and the fiber length fields to the magnetic resonance imaging data; generating an electronic image representing the first plurality of brain fiber tracts using the calculated positional coordinates and orientations thereof; and outputting the electronic image in a visual form.
