This is the first release of a data processing library which comes with it's own server-client for creating, recording, and processing event-based markers into trials/epochs/segments. It is used for raw data that is obtained through the Pupil Labs eye tracker. It also has the capability to work with Lab Streaming Layer (LSL) and process eye tracker data that is obtained through that synchronization tool. It is a Matlab package that provides a breakdown of the eye tracker data into event-based segmentation's with custom trial sizes, in both time and number of points. These can be processed even further by correcting for baseline means and obtaining percent change representations of the data relative to the baseline mean. Furthermore, there is functionality available for conducting group analysis and filtering the data.
