FAQ

Why does my tract file only overlay on one of my volumes?

The tract files are associated with the first image specified in the --nifti argument and by default will only be overlaid on that volume.

However, all volumes in the --nifti list are assigned to a common frame of reference (encoded in the dicom). It is possible to accept this registration in the Image Fusion module in Brainlab. Accepting the registation will allow tract and othe objects to be overlaid on any volume.

What is wrong with the image brightness?

Karawun does not rescale nifti data. Try rescaling by hand before converting if default brightness is a problem. Nifti scaled to a range of 0 to 1 will not display properly. Try multiplying by 10000 before conversion and test whether the situation improves.
