%'time_series': extract a time series, used with series.fig
% this function can be used as a template for applying a global operation on a series of input fields
%------------------------------------------------------------------------
% function GUI_input=time_series(Param)
%
%%%%%%%%%%% GENERAL TO ALL SERIES ACTION FCTS %%%%%%%%%%%%%%%%%%%%%%%%%%%
%
% This function is used in four modes by the GUI series:
%           1) config GUI: with no input argument, the function determine the suitable GUI configuration
%           2) interactive input: the function is used to interactively introduce input parameters, and then stops
%           3) RUN: the function itself runs, when an appropriate input  structure Param has been introduced. 
%           4) BATCH: the function itself proceeds in BATCH mode, using an xml file 'Param' as input.

%OUTPUT
% GUI_input=list of options in the GUI series.fig needed for the function
%
%INPUT:
% In run mode, the input parameters are given as a Matlab structure Param copied from the GUI series.
% In batch mode, Param is the name of the corresponding xml file containing the same information
% In the absence of input (as activated when the current Action is selected
% in series), the function ouput GUI_input set the activation of the needed GUI elements
%
% Param contains the elements:(use the menu bar command 'export/GUI config' in series to see the current structure Param)
%    .InputTable: cell of input file names, (several lines for multiple input)
%                      each line decomposed as {RootPath,SubDir,Rootfile,NomType,Extension}
%    .OutputSubDir: name of the subdirectory for data outputs
%    .OutputDir: directory for data outputs, including path
%    .Action: .ActionName: name of the current activated function
%             .ActionPath:   path of the current activated function
%    .IndexRange: set the file or frame indices on which the action must be performed
%    .FieldTransform: .TransformName: name of the selected transform function
%                     .TransformPath:   path  of the selected transform function
%                     .TransformHandle: corresponding function handle
%    .InputFields: sub structure describing the input fields withfields
%              .FieldName: name of the field
%              .VelType: velocity type
%              .FieldName_1: name of the second field in case of two input series
%              .VelType_1: velocity type of the second field in case of two input series
