function out=legTrackerPrepMedFilt(data,w)
%legTrackerPrepMedFilt takes instrument data and returns a w-frame median 
%filtered version of it. 
%Usage:
%out=legTrackerPrepMedFilt(data,w)
%data = 24004x15 concatenated training data set
%w = size of median filtering window

%boundaries between particular flies in the training data set, each fly to
%be filtered indendently
binRange=[1 8000;8001 12001;12002 16002;16003 20003;20004 24004];

%parse out data
