Tracked data files, different backgrounds

Data from males flies paired with differently painted dummies in one of three chambers -- black, white, or grey. *.m files, with the following data structs: fly (position and orientation of fly during the trial), robot (position and orientation of robot), chases and chases2 (starts and ends of chases, each uses slightly different criteria to define a chase. data from chases struct used in paper), magloc_on_flyazi (matrix with the location of the magnet on the fly's azimuth at each time step). Data come from 10 minute trials.
