Hi All,

I need some help debugging my code. It's something minor (I hope), but I can't seem to figure it out.

AbData = rand(756909,16); %%dummy data
tim_trl = 0:3.9634883453625200E-05:30-3.9634883453625200E-05; %%dummy time
t1 = 20; %start time, seconds
t2 = 30; %end time, seconds
ind1 = find(tim_trl>=t1, 1);
ind2 = find(tim_trl>=t2, 1); %10s time frame
time1 = tim_trl(ind1:ind2);
sampRate = 24414; %sampling freq (Hz), samples per sec
muaWindow = 0.001; %1ms window
binWidth = round(muaWindow*sampRate); %24 samples per 1ms
threshold = 0.018; 
for channel = 1:16
    
    data = AbData(ind1:ind2,channel);   
    counterMUA = 1;  % needed for mua indexing
    windowSt = 1;  % set start point of window
    for bin = 1:10000
        
        %set end point of window
        windowEnd = binWidth + windowSt - 1;
        
        % access data in one bin
        bindata = data(windowSt:windowEnd, channel); %debug here
        
        %%calculate mua above threshold
        mua(counterMUA, channel) = sum(bindata >= threshold);
         
        counterMUA = counterMUA+1;
        
        %slides window
        windowSt = windowSt + binWidth;
        
    end
end

This is the line of code that needs debugging:

bindata = data(windowSt:windowEnd, channel); %debug here

I know the index in position 1 exceeds array bounds, but I'm not sure how to overcome it.

Thanks in advance.
