rpwang@stage.nitrcce.org (Ruopeng Wang) — Tue, 16 Mar 2010 18:48:00 GMT

version 0.6
* Added support for more flexible gradient table format (DTI only). b0 (0, 0, 0)
vector as well as b values (as 4th component) can be included in gradient table.
Thus, it allows reconstructing data with multiple high b values.
* Added option to track by 2nd or 3rd eigenvector (DTI only).
* Added track_merge command-line tool.

TrackVis 0.5.1

rpwang@stage.nitrcce.org (Ruopeng Wang) — Tue, 16 Mar 2010 18:38:00 GMT

* Added save all end points function.
* A few bug fixes.

TrackVis

version 0.5
* New field added in .trk file header. A 4x4 rotation matrix from voxel to RAS coordinate is saved in the header.
* Able to load segmentation volume with a look up table. ROI can be created based on the segmentation.
* Able to save trackgroup as VTK file in RAS coordinate so that it can be loaded in other VTK compatible visualization software.
* Added "Save all trackgroups" option.
* Added "Save all ROIs" option.

version 0.5
* Added BCC DSI table (124 directions).
* Improved track_transform tool. It resamples a track file into a new one with given registration matrix.
* Added track_info command-line tool.
* Removed the annoying debug information from nifti libs.
