when having multiple bundle data loaded onto Slicer, is there a way to select multiple files at the same time and to change the visualization type (under Diffusion/Tractography/Tractography Display) to Tubes instead of Slices?
Slightly related, when trying to visualize the 2D interesection of the streamlines, clicking on the Tubes Slice toggle has no effect unless I also select the Tubes visualization mode for the 3D scene. Is this expected? Can this be improved (i.e. not requiring the 3D visualization to be set to Tubes manually, or by making the 3D visualization automatically switch to Tubes)?
Most of the interaction modes in the Tractograpy Display module were designed before we started working with hundreds of bundles, so they are more suited to working with a few manually created tracts. If you want to control lots of tracts in bulk the best way is to write little custom python scripts that set up things in the way you want.
