Objective

To test 2-tensor tractography in Slicer3/standalone and hook it up to full-brain clustering pipelines.

Approach, Plan

Our goals for the project week are to update clustering I/O to read tracts as a single large polydata file per subject, and to produce output in Slicer3 MRML format.

I could use help regarding the best way to have Slicer3 run a script to produce MRML. My matlab code writes a script that currently is run by Slicer2, in order to append polydata into clusters, and produce a MRML file pointing to the clusters, that includes colors derived from matlab clustering.

The next step is to ascertain what needs to be done to visualize/label the clusters in slicer3 or 4. This is in order to make atlases or study a particular tract. The old slicer2 interface allowed interactive selection of clusters (show/hide selected, and show/hide labeled or unlabeled) and anatomical naming/labeling.

Progress

Attempted to compile standalone and module 2-tensor Kalman filter tractography on a Mac. Installed Slicer3/4. Tested installation of clustering.
