Dear MRtrix experts,
I am trying to find a method to extract tracks starting from one gray matter region, traversing a white matter ROI, to another gray matter region.
I’ve read a few posts related to this question, but it seems there is no one best way to do it.
Basically, I’ve read about three ways to do this:
- do whole brain tractography with dynamic seeding; then do SIFT; then do tckedit with include regions. (Finding tracts from one region to another region)
- use tckgen to do targeted tractography with ROI induced constraints. (Tckedit or tckgen for tract dissection)
- Merge targeted tracking pathways with whole brain tractogram; then do SIFT; then do tckedit with include regions. (Tckedit after targeted tracking)
I am wondering what are the differences among these methods, especially between method 1 and method 3 and which one I should use in my case.
Sorry if my questions are too basic and thank you in advance for your kind help!
