Vicon Nexus 2.1.1 contains fixes for issues that were reported following the release of Nexus 2.1, including the following:
❙ SCoRE and SARA dynamic calculation operations now produce outputs.
❙ The issue of the cross-plate strikes option in the dynamic Plug-in Gait operation always combining data from plates if the foot strikes are manually assigned to a segment has been corrected. The Static Head Offset values are now calculated by the Plug-in Gait Static operation.
