The WU-Minn HCP Consortium is pleased to announce that version 1.2.0 of Connectome Workbench (WB) brain visualization and analysis software is now available at http://humanconnectome.org/software/get-connectome-workbench.html  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.

New features in WB v1.2.0 include:

wb_view:

  • Annotations are a powerful new feature for placing text and symbols within wb_view tabs and windows. They enable generation of publication-ready figures without the need for further annotation in a separate application (e.g., Photoshop).  Annotation features are extensively documented in “Guide to WB Annotations”.
  • New options for locking the aspect ratio for tabs and windows when converting between Tile Tabs and single tile views and when adjusting the wb_view viewport (aka viewing area).
  • Improved control over gaps and margins between tabs.
  • More flexible control over color bars and associated labels.
  • Refinements to scene files, including the option to override the user’s default background/foreground color settings.
  • Separate panning and zooming enabled between left and right hemisphere flatmaps.

Refinements to wb_command:

    -surface-average now takes per-surface weights, uses much less memory

    -spec-file-relocate changes the location of a spec file relative to its data files

    -scene-file-relocate changes the location of a scene file relative to its data files

    -label-to-volume-mapping – new command, uses ribbon mapping method

…plus many refinements to existing commands and also various bug fixes.

You will also notice in the Scenes window, some reference to BALSA Scene and Study IDs. These are WB features that will become useful in the soon to be released Brain Analysis Library of Spatial Maps and Atlases (BALSA) database (stay tuned!).

WB v1.2.0 is compatible with the WB v1.0 tutorial and the processed 900 Subjects Group Average Data available to download at http://humanconnectome.org/software/get-connectome-workbench.html and on the ConnectomeDB HCP project page. Access to both datasets require ConnectomeDB login and signature of the HCP Open Access Data Use Terms.

To download the WB v1.2.0 source code from GitHub: follow the link, click releases (near the top of the page), then under v1.2.0, click the “Source code (zip)” or “Source code (tar.gz)” button.

We encourage you to check out Connectome Workbench v1.2.0 for visualizing and performing analysis on imaging data from the HCP and elsewhere and for making scenes and figures. Discussion of Connectome Workbench usage, bugs, and features can be posted to the hcp-users discussion list. Sign up for hcp-users at http://humanconnectome.org/contact/#subscribe
