+% use a single geometric calibration, with information on the slice positions in case of 3D scanning
+%------------------------------------------------------
+% the output file indexing is based on the xml file requested by the
+% function when it is selected (or possibly inserted in this function in the section TEST)
+%  This xml file must contain the following information:
+%   NbDti: the number of 'bursts' -1
+%   NbDtj: number of frames in each burst-1, or number of repetition of a burst sequence defined by Dtj
+%   NbDtk: number of repetitions of a slice scanning process -1 (ignored by default)
+% Therefore the total number of frames is  (NbDti+1)*(NbDtj+1)*(NbDtk+1)
+% The frame series is stored in a single folder with two indices i:(NbDti+1)*(NbDtk+1) 
+%
+% To run the function in the cluster in parallel for each multitif file, indicate nb-slice_i equal to the
+% number input multitif files
