[Camino-users] tractography on a normalized tensor data

[Alexander, Daniel]

Hi,

Using the original schemefile is not perfect, but not unreasonable.  It is hard to think of a better way to do it if you really have to track in the MNI space.  The other option of course is to track in the native space and transform the streamlines into MNI space instead, which avoids some of these complications.

Since, I have normalized tensors, I was thinking of PICO but then I only have schemefile for the tensor in native space, not in MNI. Can I use the same schemefile?Or, should I use a different model altogether, and how?
