FBR files are text files containing the fiber coordinates. The fiber data in the *.fbr format can be checked via any text editor.

Newer information (see DTI Getting Started Guide 1.1):
This is the coordinate system in the OpenGL/3D Viewer window.
Origin: [x, y, z] = 0.5*VMR slice X-resolution, 0.5*VMR slice Y-resolution, 0.5*number of slices
x-axis: anterior to posterior 0 to X-resolution
y-axis: superior to inferior 0 to Y-resolution
z-axis: right to left 0 to Z-resolution
