3.0.2 changelog

Multiple commands

  • Fixel overwrite: Prevent overwrite of fixel directories even with -force and provide instruction to manually erase (thanks @Antonin_Skoch for report).

  • MatLab: Fix write_mrtrix() function when running in MatLab rather than GNU Octave (thanks @julien for report).

  • NIfTI:

    • qform: Fix erroneous warning about non-rigid transformation on image write (thanks @anna_de for report).

    • Version 2: Fix image read.

  • Piped images: Fix specific instances where the utilisation of image piping image would not result in deletion of the temporary file; these files could therefore progressively take up space in /tmp/ (thanks @tomw for report).

  • Statistical inference: Fix strong family-wise error control.

Individual commands

  • convert_bruker: Fix DW scheme handling (thanks dgrens for report).

  • dwi2fod: Fix error when certain image volumes were not assigned to b-value shells (thanks @nadluru for report).

  • dwifslpreproc:

  • mrgrid: Ensure that when nearest-neighbour interpolation is used, oversampling is disabled (thanks @leonyichencai for report).

  • mrhistmatch: Fix “scale” and “linear” modes not working in some circumstances (note: solution applies in the context of dwicat also).

  • mrtransform: Prevent erroneous warning of “DW gradients not correctly reoriented” that would occur in the scenario where a linear transformation is applied, but the input image did not contain a diffusion gradient table to begin with.

  • mrview: Fix compilation on Qt4 (thanks @zhuopinsun and @Javier_Navas for reports). Note that support for Qt4 will be removed in future update 3.1.0.

  • run_tests: Enable use not only when MRtrix3 is compiled from source, but also for testing of binary packages.

  • sh2peaks: Fix occasional segmentation fault when using -peaks option.

  • tckgen: Fix tracking at inferior edge of spinal column when DWI data include zero-filling at inferior edge of image FoV (thanks @cbajada for report).
