10%INPUT:
11% In run mode, the input parameters are given as a Matlab structure Param copied from the GUI series.
12% In batch mode, Param is the name of the corresponding xml file containing the same information
13% when Param.Action.RUN=0 (as activated when the current Action is selected
14% in series), the function ouput paramOut set the activation of the needed GUI elements
15%
16% Param contains the elements:(use the menu bar command 'export/GUI config' in series to
17% see the current structure Param)
18%    .InputTable: cell of input file names, (several lines for multiple input)

25%             .RUN =0 for GUI input, =1 for function activation
26%             .RunMode='local','background', 'cluster': type of function  use
