User Interface

The viewers are highly customizable:

  • All panels can be hidden, undocked, stacked, or repositioned on the fly.
  • Right-click on the title bar of a visible panel to restore hidden panels.
  • Double-click in the plotting region of many viewers to open an options window with additional customization controls.

Time is easy and intuitive to navigate:

  • Pressing the play button will scroll through data and video in real time, or at a higher or lower rate if the speed parameter is changed.
  • The arrow/WASD keys allow you to step through time in variable increments.
  • Dragging the horizontal slider moves through time quickly.
  • Jump to a time by clicking on an event in the event list or a table entry in the epoch encoder.

It is also easy to quickly adjust scale and placement:

  • To show more or less time at once, right-click and drag right or left to contract or expand time.
  • Press the auto scale button to automatically scale signals and color maps.
  • Scroll the mouse wheel to zoom in a trace viewer or a video viewer, or to rescale the color map in a time-frequency viewer.
  • Scroll the mouse wheel on a trace label to adjust the scale of an individual trace (by_channel scale mode only).
  • Left-click and drag on a trace label to adjust its vertical offset, or in a video viewer to reposition the video frame.
  • Adjust scale mode (real vs arbitrary units) and individual signal gains and offsets in the detailed options window of the trace viewer (double click to open).

The epoch encoder has many modes of interaction as well:

  • Click “Show/hide range” (shortcut: r) to toggle the display of a time range selector, which can be positioned with the mouse or by using dedicated buttons (labeled “>”; shortcuts: [ and ]).

  • Customizable key bindings (default: number keys) allow you to fill the selected time range with an epoch if the selector is enabled, or to place new epochs of a fixed (and adjustable) duration at the current time if it is disabled.

  • Click on an epoch to select the corresponding entry in the epoch encoder’s data table, where you can change the label associated with it.

  • Click on a row in the data table to jump to the start of that epoch.

  • Double-click on an existing epoch to enable the time range selector and position it on that epoch.

  • Toggle between epoch insertion modes using the radio buttons or modifying shortcut key presses with the Shift key:

    • Mutually exclusive mode: Placing an epoch where there is already one will delete the overlapping portion of the old epoch.
    • Overlapping mode: Epochs are permitted to overlap.

  • Merge overlapping and adjacent epochs of the same type with the “Merge neighbors” button.

  • Fill gaps between epochs using the “Fill blank” button.

  • Click “Save” (shortcut: Ctrl+s, or Cmd+s on Mac) to write the epochs to a file.
