Interactive tools

pypillometry has two interactive tools that open in their own window. They use VisPy for fast OpenGL rendering, so even long recordings (60+ minutes at 1000 Hz) can be browsed smoothly.

view(): browse recordings

Explore an EyeData object or numpy arrays: zoom, scroll, show masked regions and events, overlay several signals and select regions. Also available from the command line as pypilview.

GPU-Accelerated Viewer (pp.view)

tweak(): tune parameters

Tune the parameters of a function (e.g., a filter or blink detection) while you see the result on the data.

Interactive Parameter Tweaking (pp.tweak)

Both tools share their keyboard shortcuts. Press H or ? in the window to see them.

Note

The tools need a display. They do not work on headless servers or in Binder sessions.
