Tools

The Tools menu section represents a shortcut menu that integrates useful options related to model, acquisition, event and marker. More details on these tools are available in the section Tools / Data processing.

  • Model:
    • Create a new segment
  • Acquisition:
    • Zoom frames of interest, crop frames of interest or reframe from one the loaded acquisition.
  • Event:
    • Gait Event Detection: Chose detection and mapping methods to detect gait events. This will overwrite existing events or Append to existing events, as selected.
    • Insert, edit (Ctlr+E), remove (Del) or clear events. This can be also done by using several shortcuts
      • Alt + 1: Insert foot strike

    • Create an average marker by selecting a minimum of two markers
    • Compute and plot distance between two selected markers
    • Compute and plot angle between three selected markers
    • Compute and plot angle between two vectors by selecting three or four markers
  • Analog:
    • Remove offset: Possible for reference or selected frame)
    • Filter analog (Butterworth): Apply Butterworth filter for specific or all analog channels with the selected Filter options (Type, Zero Lag, Order, and Cutoff). This will overwrite or create new channels, as selected.
    • Rectification: Overwrite selected analog channels data or create new analog channels.
    • Scale: Scale selected analog channels using scaling rules options. This will overwrite or create new analog channels, as selected.
    • Smooth / Linear Envelop: Smooth selected analog channels using Smoothing methods (Root Mean Square / Moving average) options. This will overwrite or create new analog channels, as selected.

Window

In the window section you have the possibility to change the actual layout and / or save the current configuration. The first three layouts are predefined in the software. You can switch easily between layout using the key Ctrl (Command for MacOS X) and the index of the layout. Only the first ten layouts have a shortcut.

  • Layouts:
