Any tractogram can be fed to the COMMIT framework, as long as each tract is represented as a polyline, i.e. sequence of consecutive segments. At the moment, however, COMMIT only reads tractograms in the TrackVis file format, but additional format will be accepted in the future. Meanwhile, several converters between file formats are available (e.g. DIPY); we apologize for this inconvenience.
The old MATLAB version is still available as a tag in the repository. Please note, however, that this version is no longer mantained.
We decided to re-implement our tool in Python with the aim to be more compatible with existing tools and libraries in the field, in particular DIPY, and allow an easier integration in existing pipelines.
