Processing of events and samples will depend on what type of analysis is to be
performed. For many cognitive eye movement analyses, MSG line text specifying
experimental conditions, EFIX event data, and BUTTON event times from each
block are used to create data files for statistical analysis. For neurological
research, samples between SFIX and EFIX events can be processed to
determine smooth-pursuit accuracy and gain. In some cases, an entire block of
samples may need to be read and stored in data arrays for more complex
processing. For all of these, the organization and contents of the ASC files have
been designed to simplify the programmer's task.
