Glitter is a Python-based, Glitter screenshots touchscreen-enabled coder for post hoc video scoring, designed for studies of animal behavior.  Its particular strength is its flexibility for many types of coding, from manual XY location tracking of multiple animals (with editing) to the coding of user-defined behavioral states or events.  Playback rates are adjustable on the fly, from frame-by-frame stepping to hyper-realtime playback.

Screenshots are available illustrating head-tracking during an odor sampling task, a zoomed-in view of that same frame for fine-scale editing, investigating a rewarded cup versus a non-rewarded cup, and tracking in an open field.

Glitter is in routine use in the lab but is not yet well documented.  Upon release it will be freely available from this website; until that time it can be downloaded from Github.
