So, how similar are your bundles to the real anatomy? Learn how to optimize your analysis as we did to create the fornix of the figure above, by reading the tutorials in our gallery.

In DIPY we care about methods which can solve complex problems efficiently and robustly. QuickBundles is one of the many state-of-the-art algorithms found in DIPY. It can be used to simplify large datasets of streamlines. See our gallery of examples and try QuickBundles with your data. Here is a video of QuickBundles applied on a simple dataset.
