Hi Nuua –
Just to clarify what you are trying to do : do you basically want to sample the BrainSuite generated tracks into an image volume? Are you looking for a simple binary mask or a tract density map?
We do have some code to do these things. The first is in Matlab, and you can download the source code here:
Will that provide what you need?
We also have some additional C++ command line tools for this that we haven’t released it publicly yet. I expect we will have those available in the next two weeks.
