MRtrix3Tissue v5.0.0

This release brings in a series of upstream MRtrix3 developments and bug fixes. The most critical bug fixes relate to population_template, which now works again as originally intended. The other most important updates and changes end users should be aware of include:

• dwipreproc has been renamed to dwifslpreproc
• it's now mandatory to specify to mrtransform whether to perform FOD reorientation (-reorient_fod yes) or not (-reorient_fod no)
• mrtransform has a new -modulate option to perform intensity or FOD modulation
• several changes and improvements to dwidenoise: new noise estimator, new edge voxel handling and a new default patch size based on the number of volumes; check the dwidenoise command line documentation for detailed information.
• several changes and improvements to mrthreshold, resulting in a new interface and options.
• more precise variance (and consequentially also standard deviation) calculation by mrmath and mrstats
• several changes to complex data handling by mrcalc
• a bug fix for foreach to avoid duplicated jobs when multi-threading

The dwi2response dhollander algorithm has been tested to continue working as before after the changes to mrthreshold.

The private SS3T-CSD beta implementation has been successfully rebased on this new release and compatibility has been validated. After about 1.5 months of private beta testing, feedback and improvements to the interface, default operation and overall robustness, we're now nearly ready to transition to a public (beta) release. A heartfelt thank-you to the private beta test users: your feedback has helped me to reach this goal. A great reminder that engaging with users is a good thing.
