6%filebasesub: filename without appendix
7%field_count: string for the first number i
8%str2: string for the second number i (only for .nc files)
9%str_a: string for the first number j
10%str_b:string for the second number j (only for .nc files)
11%ext: file extension
12%nom_type: char chain characterizing the file nomenclature: with values
13%   nom_type='': constant name [filebase ext] (default output if 'nom_type' is undefined)
14%   nom_type='*':constant name for a file representing a series (e.g. avi movie)
15%   nom_type='1','01',or '001'...': series of files with a single index i without separator(e.g. 'aa045.png').
16%   nom_type='_1','_01','_001'...':  series of files with a single index i with separator '_'(e.g. 'aa_045.png').
17%   nom_type='1a','1A','01a','01A',... with a numerical index and an index letter(e.g.'aa45b.png') (lower or upper case)
18%   nom_type='_1a','_1A','_01a','_01A',...: idem, with a separator '_' before the index
19%   nom_type='_1_1','_01_1',...: matrix of files with two indices i and j separated by '_'(e.g. 'aa_45_2.png')
20%   nom_type='_i1-i2': from pairs from a single index (e.g. 'aa_45-47.nc')
21%   nom_type='_i_j1-j2': pairs of j indices (e.g. 'aa_45_2-3.nc')
22%   nom_type='_i1-i2_j': pairs of i indices (e.g. 'aa_45-46_2.nc')
23%   nom_type='_1_ab','1_ab','01_ab'..., from pairs of '#' images (e.g.'aa045bc.nc'), ext='.nc'
24%subdir: name of the subdirectory for netcdf files
