5% OUTPUT:
6% RootPath,RootFile: root path and root name detected in fileinput, possibly modified for movies (indexing is then done on image view, not file)
7% i1_series(ref_i, ref_j,pair),i2_series,j1_series,j2_series: set of indices (i1,i2,j1,j2) sorted by ref index ref_i, ref_j, and pairindex in case of multiple pairs with the same ref
8% NomType: nomenclature type corrected after checking the first file (problem of 0 before the number string)
9% FileType: type of file, =
10%       = 'image', usual image as recognised by Matlab
11%       = 'multimage', image series stored in a single file
12%       = 'civx', netcdf file with civx convention
13%       = 'civdata', civ data with new convention
14%       = 'netcdf' other netcdf files
15%       = 'video': movie recognised by VideoReader (e;g. avi)
16% Object: video object (=[] otherwise)
17%
18%INPUT
19% fileinput: name (including path)  of the input file
