function [PSTH ]=UTIL_PSTHmakerb(inputData, dt, PSTHbinWidth)

% UTIL_PSTHmakerb averages mean values into bins.

% No corrections are applied

% usage:

%	PSTH=UTIL_PSTHmaker(inputData, method)

%

% arguments

%	inputData is a channel x time matrix

%	PSTH is the reduced matrix, the sum of all elements in the bin

%

[numChannels numDataPoints]= size(inputData);

% Multiple fibers is the same as repeat trials

% Consolidate data into a histogram 

dataPointsPerBin=round(PSTHbinWidth/dt);

if dataPointsPerBin<=1;

% 	Too few data points

	PSTH=inputData;

	return

end

numBins=floor(numDataPoints/dataPointsPerBin);

PSTH=zeros(numChannels,numBins);

% take care that signal length is an integer multiple of bin size

%  by dropping the last unuseable values

useableDataLength=numBins*dataPointsPerBin;

inputData=inputData(:,1:useableDataLength);

for ch=1:numChannels

	% Convert each channel into a matrix where each column represents 

	% the content of a single PSTH bin

	PSTH2D=reshape (inputData(ch,:), dataPointsPerBin, numBins );

	% and sum within each bin (across the rows

	PSTH(ch,:)=mean (PSTH2D,1);
