5%OUTPUT:
6%RootPath: path to the base file
7%SubDir: name of the SubDirectory for netcdf files (NomTypes with index pairs 1-2 or ab )
8%RootFile: FileName without appendix
9%i1: first number i
10%i2: second number i (only for .nc files)
11%j1: first number j
12%j2: second number j (only for .nc files)
13%FileExt: file Extension
14%NomType: char chain characterizing the file nomenclature: with values
15%   NomType='': constant name [filebase FileExt] (default output if 'NomType' is undefined)
16%   NomType='*':constant name for a file representing a series (e.g. avi movie)
17%   NomType='1','01',or '001'...': series of files with a single index i without separator(e.g. 'aa045.png').
18%   NomType='1a','1A','01a','01A','1_a','01_A',... with a numerical index and an index letter(e.g.'aa45b.png') (lower or upper case)
19%   NomType='1_1','01_1',...: matrix of files with two indices i and j separated by '_'(e.g. 'aa45_2.png')
20%   NomType='1-1': from pairs from a single index (e.g. 'aa_45-47.nc')
21%   NomType='1_1-2': pairs of j indices (e.g. 'aa_45_2-3.nc')
22%   NomType='1-2_1': pairs of i indices (e.g. 'aa_45-46_2.nc')
23%   NomType='1_ab','01_ab','01ab'..., from pairs of '#' images (e.g.'aa045bc.nc'), FileExt='.nc'
