- DICOM multi-frame support
- enhanced ROI drawing tools in MRView (courtesy of Richard Beare)

Other bug fixes and enhancements

- Clean compile on MacOSX 10.9

MRtrix version 0.2.11 released

J-Donald Tournier — Thu, 14 Mar 2013 1:22:00 GMT

MRtrix version 0.2.11 is now available for download. This is a minor release with the following key enhancements:

- compressed NIfTI support (*.nii.gz)
- DICOM multi-frame support
- variable brush size in MRView ROI tool
- a few files to help set up MIME types and icons under Linux (just run ./install_mime_types)

Other bug fixes:
- generate NIfTI images that won't crash FSLView (i.e. when 4th dimension is zero)
- fix bug that resulted in NaNs in response function
- fix bug in handling of temporary files when no write permission to current working directory
- streamtrack's -stop option now tracks bidirectionally as expected
- various compilation fixes
- other minor bug fixes (see change log for details)

Note that the Python interpreter in the build script is now explicitly invoked as 'python2', since on newer systems 'python' defaults to Python version 3, which will only abort with unhelpful error messages. If you get 'bad interpreter' error messages, either edit the first line of the 'build' file to point to the correct Python version 2 executable, or create a symbolic link to it called 'python2' somewhere in your path, e.g.:

# ln -s /usr/bin/python /usr/bin/python2

- easier install via './build install'
- support for MacOS X
- new filter_tracks command to edit tractography output after tracking

- new MatLab scripts to read/write MRtrix image and track files
- new features in MRView:
- images can be loaded into viewer using drag & drop;
- position of focus can be dropped onto command-line by dragging from statusbar
- faster rendering of FOD overlay
- other minor bug fixes

Other more minor changes:

- new length-scaled TDI option in tracks2prob
- '-stop' option in streamtrack now stops once all include ROIs have been reached
- for NIfTI: both qform and sform entries are now written with equivalent transform information
- other minor bug fixes (see full changelog for details).

MRtrix Version 0.2.8 released

J-Donald Tournier — Wed, 14 Apr 2010 2:55:33 GMT

This is mostly a bug fix release, but there are a few important changes:

- a few minor bug fixes to work on latest distributions, in particular Ubuntu 9.10;
- new preliminary DICOM import of DW gradient orientations for GE and Philips;
- in streamtrack: the tracking now stop immediately before leaving the mask region, rather than immediately after

MRtrix Version 0.2.7 released

J-Donald Tournier — Wed, 26 Aug 2009 1:50:50 GMT

This release fixes a potentially problematic bug that caused incorrect scaling of the FA values. The FA values produced by previous versions of MRtrix were underestimated by approx. 22.5%. Any users that rely on MRtrix to produce FA values are urged to regenerate their FA maps using this new version.

Also included are some tools to ease integration with other spatial normalisation packages, as well as a command-line ROI statistics tool.

MRtrix Version 0.2.6 released

J-Donald Tournier — Thu, 19 Mar 2009 1:29:48 GMT

This release fixes a serious bug in the "streamtrack" tracking program. This bug caused incorrect tracking results in cases where the DWI data sets were acquired in an oblique plane.

MRtrix users are STRONGLY urged to upgrade immediately, and to regenerate tracking results for any obliquely acquired data sets. Further information will be released on the MRtrix mailing list (http://www.nitrc.org/pipermail/mrtrix-discussion/).

This release also includes a few performance enhancements, and fixes a number of minor bugs.

MRtrix Version 0.2.5 released

J-Donald Tournier — Wed, 03 Sep 2008 1:19:08 GMT

This release introduces NIfTI support, allowing interaction with other packages such as SPM5 and FSL. This is particularly useful for performing coregistration of anatomical images with the DWI.

Also included is a new FAQ section, with a fairly detailed description of how to coregister using either SPM5 or FSL.

There are also a few very minor bug fixes.

Version 0.2.4 released

J-Donald Tournier — Mon, 04 Aug 2008 2:49:02 GMT

This release provides two new features:
- an overlay of the orientation plots on the main viewer window (see the screenshot section),
- support for 64-bit (x86-64) systems.

Also included are a few more minor bug fixes.
