8% ParamOut: sets options in the GUI series.fig needed for the function
9%
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)
19%                      each line decomposed as {RootPath,SubDir,Rootfile,NomType,Extension}
20%    .OutputSubDir: name of the subdirectory for data outputs
21%    .OutputDirExt: directory extension for data outputs
22%    .Action: .ActionName: name of the current activated function
23%             .ActionPath:   path of the current activated function
24%             .ActionExt: fct extension ('.m', Matlab fct, '.sh', compiled   Matlab fct
25%             .RUN =0 for GUI input, =1 for function activation
26%             .RunMode='local','background', 'cluster': type of function  use
27%             
28%    .IndexRange: set the file or frame indices on which the action must be performed
29%    .FieldTransform: .TransformName: name of the selected transform function
30%                     .TransformPath:   path  of the selected transform function
31%    .InputFields: sub structure describing the input fields withfields
32%              .FieldName: name(s) of the field
33%              .VelType: velocity type
34%              .FieldName_1: name of the second field in case of two input series
35%              .VelType_1: velocity type of the second field in case of two input series
36%              .Coord_y: name of y coordinate variable
