That is not going to work for such a large file.<br>

You can use tractshredder to either downsample the tracts, or split them into different files, then run vtkstreamlines.<br>

However when I run the command: vtkstreamlines <bayesianTrack.Bfloat> bayesianTrack.vtk , I get the error: "Exception in thread "main" java.lang.OutOfMemoryError: Java heap space". I tried to increase CAMINO_HEAP_SIZE as far as 28000!! but I still get the error. When I try to go higher (eg. 30000) I get: "Aborted (core dumped). Does anyone know how I can get around this?<br>
