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);

% 	Too few data points
	PSTH=inputData;

% take care that signal length is an integer multiple of bin size
%  by dropping the last unuseable values

	% Convert each channel into a matrix where each column represents
