find and download abcd tractography #8

Closed ebrahimebrahim closed 3 months ago

I learned recently that there is actually pre-computed tractography in the ABCD datatset. If that's true and we can get a hold of it then it might provide a way to simplify https://github.com/brain-microstructure-exploration-tools/abcd-registration-experiments/issues/3

We also would need to understand how those tracts were generated of course

Hmm I cannot seem to find them.

Martin explicitly said there is no tractography so I must have been mistaken thinking there was. Closing.

It turns out that the idea is to download AtlasTrack from NITRC and register subject images to it and then pull back the tracts provided by AtlasTrack into subject space.

However (a) AtlasTrack is full of matlab related files and so seems pretty unpleasant to work with and (b) we shouldn't bias our registration evaluation results with another registration to a particular atlas. Tractography in subject space will be a better evaluation.
