 2) The quantifications are summarized in a figure that is exported to a .PNG and .PDF file (see link below). The visualizations are done for one-hour segments (per page) and contains general recording information (top left), jump detections (bottom left), time courses of the head positions, raw signal, power line noise (50 or 60 hz), and low frequency noise (0 - 2 Hz) in top right. Furthermore,​ the average power spectrum (bottom middle) and the triggers present in the dataset, where '​values'​ represents the number of unique triggers detected (i.e. same value, bottom right). 2) The quantifications are summarized in a figure that is exported to a .PNG and .PDF file (see link below).
