To hcp-users, We just discovered and fixed a bug in Connectome Workbench (v 0.8) that was preventing access to group-average maps of functional connectivity (a capability described in the tutorial that accompanies the recently announced Q1 data release).
Version 0.81 (with the bug fix and a few additional features) is now available at http://www.humanconnectome.org/connectome/get-connectome-workbench.html David Van Essen, on behalf of the Workbench development team.
