 The goal was too lofty but the week was excellent.

+* Had a lot of great discussions and good insight into what others are doing.
 * Got working on acquiring data from different sources (more problems are always welcome!)
 * Shared some experiences.

 * Figure out anyone is in need of DWI registration for testing, have a dataset already registered (for comparison), or can help with anatomical landmarks.

 * '''Objective''': Evaluate/validate a density-based non-rigid registration framework for DWI (see the link below for a paper on similarity measure used). <br>''In short: Is this a good registration?''
-* '''Short description''': The model is based on Free-Form Deformation B-splines where the directions are updated using the normalized Jacobian. B-spline interpolation is used spatially, the Watson Distribution is used directionally. Histogram is smoothed. Similarity is NMI and optimisation is L-BFGS.
+* '''Short description''': The model is based on Free-Form Deformation B-splines where the diffusion gradient directions are updated using the normalized Jacobian. B-spline interpolation is used spatially, the Watson Distribution is used (gradient) directionally. Histogram is smoothed. Similarity is NMI and optimisation is L-BFGS.

 <!-- Approach and Plan bullet points -->
-* Figure out what diffusion data is available (preferably data already evaluated by another registration model).
+* Discuss best ways to validate results (tractography, biomarkers, synthetic data, phantoms, others?). So far we have visually tested inter-subject registrations of HCP data,  intra-subject multi-shell, and intra-subject on child brain tumor subjects.
-* Discuss best ways to validate results (tractography, biomarkers, synthetic data, phantoms, others?). So far we have visually tested inter-subject registrations of HCP data and intra-subject multi-shell, and intra-subject on young brain tumor subjects.
+* Figure out anyone is in need of DWI registration for testing, have a dataset already registered (for comparison), or can help with anatomical landmarks.
 * Consider if Slicer can be used in tandem for evaluation.
 * This method introduces Mutual Information to nonrigid registration of DWI. Discuss if other similarity measures (e.g. correlation measures) would be better suited for specific problems.
