10%
11%INPUT:
12% In run mode, the input parameters are given as a Matlab structure Param copied from the GUI series.
13% In batch mode, Param is the name of the corresponding xml file containing the same information
14% when Param.Action.RUN=0 (as activated when the current Action is selected
15% in series), the function ouput paramOut set the activation of the needed GUI elements
16%
17% Param contains the elements:(use the menu bar command 'export/GUI config' in series to
18% see the current structure Param)
19%    .InputTable: cell of input file names, (several lines for multiple input)
20%                      each line decomposed as {RootPath,SubDir,Rootfile,NomType,Extension}
21%    .OutputSubDir: name of the subdirectory for data outputs
22%    .OutputDirExt: directory extension for data outputs
23%    .Action: .ActionName: name of the current activated function
24%             .ActionPath:   path of the current activated function
25%             .ActionExt: fct extension ('.m', Matlab fct, '.sh', compiled   Matlab fct
26%             .RUN =0 for GUI input, =1 for function activation
27%             .RunMode='local','background', 'cluster': type of function  use
28%             
29%    .IndexRange: set the file or frame indices on which the action must be performed
30%    .FieldTransform: .TransformName: name of the selected transform function
31%                     .TransformPath:   path  of the selected transform function
32%    .InputFields: sub structure describing the input fields withfields
33%              .FieldName: name(s) of the field
34%              .VelType: velocity type
35%              .FieldName_1: name of the second field in case of two input series
36%              .VelType_1: velocity type of the second field in case of two input series
37%              .Coord_y: name of y coordinate variable
