Connectome Workbench v1.3.0 Released
The WU-Minn HCP Consortium is pleased to announce that version 1.3.0 of 
Connectome 
Workbench<https://www.humanconnectome.org/software/get-connectome-workbench> 
(WB) brain visualization and analysis software is now available for 64-bit Mac 
OSX, Windows, and Linux. The Workbench distribution includes wb_view, a 
GUI-based visualization platform, and wb_command, a command-line program for 
performing a variety of algorithmic tasks using volume, surface, and 
grayordinate data.

Notable changes in WB v1.3.0 include:
wb_view:
Best Practices Guide for creating Annotations and Scenes added to Help

Charting

  *   Chart View fully revised to include a layer-like system and support for 
histograms and for charts from many more file types.
  *   Improved and expanded options for control of axes.
  *   Old version of charting remains for compatibility with older scenes.

Annotations

  *   Improved aspect locking with notifications
  *   Warn if annotation text is too small
  *   Added new coordinate space for adding annotations in the new version of 
charting
  *   Line thickness maximum removed and line thickness scales with tab height

BALSA compatibility (BALSA = <https://balsa.wustl.edu/> Brain Analysis Library 
of Spatial Maps and 
Atlases<https://balsa.wustl.edu/><http://www.ncbi.nlm.nih.gov/pubmed/27074495><http://www.ncbi.nlm.nih.gov/pubmed/27074495>
 database for sharing analyzed data as WB scenes)

  *   Improved dialog for uploading scene file to BALSA with ability to create 
and edit BALSA study names
  *   Scene Identifiers are requested from BALSA and added to the scene file 
after successful upload of a scene file to BALSA
  *   Added automatic detection of the base path (for recreating directory 
structure of shared datasets)


Scenes

  *   Scenes window revised, including ability to save scene files directly 
without using Save/Manage Files
  *   Added List Files... button to show all data files referenced by a scene 
file
  *   Scenes reload a file if the version on disk has been modified since 
loaded into memory
  *   Warn if there are modified files prior to loading a scene
  *   Volume attributes (crosshairs, labels, etc.) are saved to scenes


Volumes

  *   Volume surface outline scales with tab height
  *   Improved sform support of non LPI oriented files
  *   Warn if a NIFTI volume file contains invalid qform and sform
  *   Added masking option for oblique slice drawing so that edge effects from 
cubic interpolation can be hidden



Miscellaneous

  *   Reading of GIFTI RGBA files is now supported
  *   Upgraded to Qt 5.7 and compilers that support C++11.  Using Qt 5.7 may 
help with some "XCB errors" encountered on Linux.

Overlay Settings

  *   Added thresholding of Overlay Layers using data from another data file 
and map
  *   Added inversion of Palettes for brainordinate coloring

wb_command:
Changes to existing behavior:

  *   corrected qform calculation in oblique or unusual orientation volume files
  *   built against QT5, on newer OSes for mac and linux
  *   surface to volume mapping defaults have changed for less overshoot and 
sharper results (volume to surface defaults are unchanged, but has option 
available for sharper results)
  *   Window->Identify... cifti index now uses 1-based indexing
  *   volume to surface myelin mapping method has been fixed to use the 
cylindrical cutoff described in the paper, with a new option to restore the old 
unintended behavior
  *   -*-stats commands now use multi-map roi files to output multiple columns 
of stats


New notable features:

  *   override map index for yoking group in -show-scene, give error message on 
command failure
  *   tab completion for wb_command (extensive) and wb_shortcuts (basic) in bash
  *   acceleration of correlation by use of SIMD instructions - thanks to 
Kristian Loewe
  *   ability to write smaller low-precision cifti using integer datatypes and 
scaling
  *   new -*-label-probability commands
  *   new strain-based surface and volume distortion measures
  *   generates warnings when writing files with incorrect extensions

Bugfixes:

  *    wb_shortcuts concatenate functions don't fail with "unbound variable"
  *   -cifti-merge-dense fixed for volume label data
  *   -cifti-parcel-mapping-to-label help corrected
  *   -cifti-create-dense-from-template handling of -cifti with voxel data
  *   GEO_GAUSS and GEO_GAUSS_EQUAL smoothing methods now use the corrected 
vertex areas in their distance computation (GEO_GAUSS_AREA, the default, 
recommended method, already used them)
