% filename - string giving name of input file

% NOTE:

% Input file-format (binary):
% (each segment in the table is a 64 bits double):
%	  1) number of channels
%	  2) number of trials
%	  3) number of samples per trial segment
%	  4) number of markers per trial
%	  5) n-doubles giving the times-array (for each sample from 1...n this array
%	     gives the corresponding time in ms)
% 	  6) num_markers*num_trials-doubles giving markers in sampling-point
% 	  units [1,...,n]
%	  7) raw EEG-data in the format of:
%	      - channels x trial x samples
%			- i.e. first all trials of the first channel one after the other, than
%			  the 2nd and so on
