This document describes how to set up your computer, and download data that will be used during the lectures and homework exercises.  This will involve running CONN to process some of the data.  That process will be slow (up to 6-hours), but it is automatic and it can be run overnight.  Please try to do that before the first day of class (if you run into problems let us know with enough time so we can address them before the first day of class).
