<div dir="ltr">Hi Michael,<div>thanks a lot for replaying soon!</div><div>I am a bit into troubles for applying the trasformation, because in the header information I get a 4x4 matrix with the spatial information, something like</div>

As a temporary fix (which worked for me) you could apply a transform to your tracts in Paraview (Filter --> Alphabetical --> Transform) to align them with your FA image, the transform parameters being in your image header. You can read the header of your Analyze image with "analyzeheader -readheader <image>" or your NIFTI image with "niftiheader -readheader <image>"</div>

I run deterministic tractography on a seed region, and would like to visualize results using paraview overlaying my FA map and the track. I use vtkstreamlines command to convert my track file, and open both FA image and the tracks. I represent Fa image as slice, and the tracts as wireframe; even if directional informations seem to be ok for correctly color coding tracts, two objects do not overlay at all. It is probably due to the loss of header informations after running track command. How do you link again such infos to the streamline in vtk format? I'm sure there is a way, as you have displayed in the tutorial.</div>
