Connectome Workbench v1.4.2 Bugfix Release
A new release of version 1.4.2 of Connectome Workbench (WB) is available. This is a bugfix release, most notably, to correct a crash that occurs when a parcel file is loaded and an identification (click or annotation on grayordinate) is made in the GUI. Full list of changes below.
The Workbench brain visualization and analysis software distribution, available for 64-bit Mac OSX, Windows, and Linux, 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.
Notes on launching Workbench: (1) wb_command must be run from a terminal window (not double-clicked on Mac or Windows); (2) wb_view may crash if used with a remote desktop due to problems with Xcb and OpenGL in the remote desktops. VirtualGL works for some users. Even if wb_view runs in a remote desktop, performance may be poor as they often use software implementations of OpenGL.
To download the WB v1.4.2 source code from GitHub: follow the link, click Releases (near the top center of the page), then under v1.4.0, click the “Source code (zip)” or “Source code (tar.gz)” button.
