    730730The actual start of the processing is triggered by pressing the button '''[RUN]'''. It can be run in local mode, i.e. on the current Matlab session, or as ''background'', by selecting this option in '''[!RunMode]'''. In mode ''background'', calculation is performed in a new Matlab session (without graphics) so that the current Matlab session is free for new operations. If a cluster system has been detected, a third option 'cluster' appears in the menu, allowing to dispatch parallel computations on a computer cluster.

    732 When '''[RUN]''' is activated the information from the GUI '''series''' is transcripted to a file .xml in a subfolder '0_XML' of the folder containing the result files. Therefore the operation parameters are preserved, and can be retrieved in the GUI''' series''' by the menu bar command '''[Open config]'''. In the modes 'background' or 'cluster', input information for the calculation is transmitted by this xml file. In the mode 'cluster', the calculation is split into sub-calculations, with an xml file for each. A sub-folder '''/0_LOG''' then contains the messages sent by the computation as a replacement of the work window display of the usual interactive Matlab mode.

    734734For the option 'cluster', a compiled version of the action function is useful, to avoid installing Matlab on each node of the cluster. This is achieved by selecting the option ''.sh'' in the menu '''[!ActionExt]'''. If the compiled version is not yet available, or outdated, the GUI proposes a new compilation of the selected function (launching the function ''compile.m'' requiring the Matlab compilator toolbox). The use of compiled function on the cluster requires a file '!RunTime' whose address needs to be specified  in the parameter file PARAM.xml of the package UVMAT. The commands in '''series''' are set for the system 'oar', but adding the equivalent commands for another cluster system is straightforward (this must be done in the sub-function ''RUN_Callback'' of ''series.m'').

    840840
    841841'''- Threshold on the velocity modulus: ''' (expressed in pixels). It can remove either excessive values (threshold set by '''[num_MaxVel]''') or too small values (threshold set by '''[num_MinVel]'''). Erratic zero velocity vectors, produced by a fixed image background, can be eliminated by the latter criterium.
