Fiber Navigator Description

With the help of Fiber Navigator you can view deterministic tractography results, including effective selection of fibers together with probabilistic tractograms. It offers support for surface texturing, MRI display, and EEG/MEG source localization.

No installation required

This is a portable package, so you can save it anywhere on the HDD and simply click the executable to launch Fiber Navigator. There is also the option to copy it to a removable storage unit to directly run it on any PC with minimum effort. It doesn’t modify Windows registry settings.

Simple interface and multiple import options

The GUI is represented by a graphical and a command-line window that run side by side. You can open files from Nifti (.nii), Mesh (.mesh, .surf, .dip), Fibers VTK/DMRI (.fib), Fibers PTK (.bundlesdata), Fibers TrackVis (.trk), Fibers MRtrix (.tck), Scene (.scn), Tensor (.nii) or ODF file types (.nii).

View data and customize settings

The app lets you view the axial, coronal and sagittal planes, toggle alpha blending mode, personalize the fiber colors, create new selection boxes or ellipsoids, adjust the x, y and z coordinates, and calculate the fiber statistics.

What’s more, you can rotate the x, y or z axis, lock slices or the scene, specify the stroke size, activate the drawer, change the map colors, disable lighting and clear to black, as well as enable a filter iso and flip normal. The current scene, selected fibers, selected surface or selected dataset can be easily saved.

Evaluation and conclusion

No error dialogs popped up in our tests, and the software tool didn’t freeze or crash. It left a small footprint on system resources, using low CPU and RAM. Too bad that Fiber Navigator is not very intuitive for less experienced users. Otherwise, it brings some powerful features to the table dedicated to viewing deterministic tractography results.
