function [outData] = demean(inData)
%DEMEAN performs baseline correction using the given time window
%   input stream is divided into trials and average voltage within the set
%   time window is calculated for each trial. Afterwards this average 
%   activity is subtracted from the whole trial to normalise activity in
%   set time window to 0.

% calculate average voltage within time window
avV = mean(inData);

% subtract average voltage from trials
outData = inData-avV;
