I am very pleased to inform you that the paper
Garyfallidis et al., "Robust and efficient linear registration of white-matter fascicles in the space of streamlines", Neuroimage 2015, is now available online here.
This link below allows for free access of the paper for a couple of weeks
The main idea is depicted in the figure below. If you have a bundle, as a set of streamlines, you can directly register it with SLR to homologous bundles. The results are very robust to incomplete data which are omnipotent in tractography.
The SLR is a killer application for the world of diffusion MRI as it allows you to:
- Register incomplete bundles of the same type from different subjects.
- Create sharp bundle-specific atlases.
- Register left to right bundles directly for lateralization experiments.
- Perform efficient whole brain linear registration.
The method is already available in DIPY and I have a simple tutorial here http://dipy.org/examples_built/bundle_registration.html#example-bundle-registration
The next days I will upload new more advanced tutorials and show you how to generate the results of the paper with your datasets.
