Hi! I am Tabinda. I have been using the Fibercup phantom simulated using Mitk-Fiberfox for evauluating different tractography algorithms and now I am trying to replicated the same Fiberfox simulated phantom. I have three queries regarding the paper "Fiberfox: Facilitating the Creation of Realistic White Matter Software Phantoms"
1. How to compute the integral given in eq (2) of the paper? (image attached) <http://mitk-users.1123740.n5.nabble.com/file/t737/image714.png> 2. I have read in other papers that weighted average is used to compute the multiple fibers in a voxel but this interpretation is new for me. I couldn't find the source code on the MITK Phabricator (https://phabricator.mitk.org/source/mitk/browse/master/Modules/DiffusionImaging/FiberTracking/Fiberfox/). 2. If I use weighted average for modeling multiple fibers in a voxel, the amplitude of fiber orientation estimated for parallel fibers doesn't add up like Fiberfox simulated fibercup (image attached) <http://mitk-users.1123740.n5.nabble.com/file/t737/image2.png> How this pattern is modeled in fiberfox? 3. In a voxel in which there is no fiber orientation (e.g. gray matter), what is the value of the anisotropic compartment? Is it zero or one? Or some specific value is given to the Tensor 'D' in case of isotropic compartment? Help regarding these queries will be highly appreciated.
