[Mristudio-users] A few questions about LDDMM transformations

[Peterson, Daniel]

Hi All,

   I've got a couple of questions:

1) What kind of re-orientation strategy does DTI Studio use when reorienting tensors for an LDDMM transformation of tensor data. Is there a reference available somewhere? As I understand, this is a non-trivial problem.

2) What do the experts here feel about the feasibility of fiber-tracking in atlas-space? I know that this is traditionally considered undesireable, but do people think that perhaps with these more advanced methods, standard-space tractography could be feasable?

3) Are there any command-line tools available for working with LDDMM transformations in a scriptable, automated manner? It would help our productivity immensely if we could apply Hmaps and Kimaps from the command-line, without clicking on buttons. Being able to combine transformation matrices programmatically would be great as well.

Thanks so much,
-Dan
