DESCRIPTION
++++++++++++++++++++++++++++


- stimulus <648000x400>:  Contains the 20 x 20 = 400 light intensity traces of the movie. These traces are bounded between 0 and 1. The stimulus contains segments with 1, 2, 4 and 10 randomly moving balls. For a description of the structure of the stimulus, see accompanying image file, ExperimentStructure.pdf. 
	

- response <648000x91>:  Binarized (0,1) response of 91 retinal ganglion cells.


- LimTraining <43x2>: 	start/end bin indices for 43 training segments (10 - balls stimulus). The training data avoids repeated stimulus segments, as it should. Each training segment is 2399 bins in length, which adds up to 103157 bins. 

- LimTesting <10x2>:	start/end bin indices for 10 testing segments (10 - balls stimulus). Also avoids repeats. 10 x 2399 = 23990 test bins in total.			  

- rep_begin_index_SEQ* / rep_end_index_SEQ* :  start/end bin indices for repeated stimulus segments.
