1%'find_file_series': check the content of an input file and find the corresponding file series
2%--------------------------------------------------------------------------
3% function [RootPath,RootFile,i1_series,i2_series,j1_series,j2_series,NomType,FileType,Object,i1_input,i2_input,j1_input,j2_input]=find_file_series(fileinput)
4%
5% OUTPUT:
6% RootFile: root file detected in fileinput, possibly modified for movies (indexing is then done on image view, not file)
7% i1_series(pair,ref_j+1, ref_i+1),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%  (ref_i+1 is used to deal with the image index zero sometimes used)
9% NomType: nomenclature type corrected after checking the first file (problem of 0 before the number string)
10% FileType: type of file, =
11%       = 'image', usual image as recognised by Matlab
12%       = 'multimage', image series stored in a single file
13%       = 'civx', netcdf file with civx convention
14%       = 'civdata', civ data with new convention
15%       = 'netcdf' other netcdf files
16%       = 'video': movie recognised by VideoReader (e;g. avi)
17% MovieObject: video object (=[] otherwise)
18%
19%INPUT
20% RootPath: path to the directory to be scanned
21% fileinput: name (without path) of the input file sample
22% checkxml: =1(default) take into account xml file existence to possibly include indexes in RootFile
23%           =0: do not take into account xml file existence
