How to import DSI Studio trk.gz files

I’ve tried converting to vtk via TrackVis, but the orientation was off and I could not figure out how to fix it.

Usually when meshes appear with unexpected orientation it is due to difference in coordinate system (LPS/RAS). If you are loading a mesh file (.vtk, .ply, .stl, … file ) and the coordinate system is not specified in the file header then Slicer assumes DICOM convention (LPS), but you can choose RAS after you select the file (in “Add data” window click on “Show options” in the top-right corner).

Load DSI Studio (*.trk.gz) or TrackVis (*.trk) tracks in Slicer

Does anyone have experience converting and then loading fibertrack generated by these software into 3D Slicer ? Is there any recommended pathway to export tracts and import them into Slicer ? We are thinking of these approaches: improve export to vtk (fiberbundle) in software like DSI Studio. add IO support for .trk.gz, .trk … Thanks for your input References: format .trk.gz: http://dsi-studio.labsolver.org/ / Subpages - DSI Studio—A Tractography Software Tool format .trk: http://www…

Diffusion module in 4.13 version cannot complete the reconstruction of fiber bundle

Win10 64 I don’t know if this is a mistake My friend and I have tried multiple versions of 4.13 Slicer But in the last step, when setting the seed to display the fiber bundle, it can’t be displayed. The same data, the same steps, the fiber bundle can be displayed normally in version 4.11. Can the developer test whether the fiber bundle can be rebuilt in the latest 4.13 version？ [捕获.PNG] This is the same mrb file in 4.11 Version[捕获]

Let us know how it works.
