%This script creates a mat file with spikes and LFP channels 1-8 of one
%data set supplied by Blackrock Microsystems that conforms to File
%Specification 2.3.
%
%The matlab code for loading data was originally provided through Blackrock
%Microsystems and was slightly modified.
%TODO: Update to newer versions of matlab file loaders provided by Blackrock.
%
%The result FileSpec2.3001.mat is used in the IO test :
% test_compare_blackrockio_with_matlabloader_V23
%
%Contents of data file:
%Raw recording on Channels 1-8
%Spike signal on Odd Channels (1-7)
%Recording on Analong Inputs 1 and 2
%Signal on Analog Input 2
%Three Comments Approximately 10 Seconds Apart
%Intermittent and Randomized Digital Signal
%No Serial Data
%No Tracking Data
