    14Open an image in UVMAT_DEMO03_PIVchallenge_2005C, representing a jet seeded by particles (accessible on http://servforge.legi.grenoble-inp.fr/pub/soft-uvmat/).

    710The lower and upper indices for the input field series are given by '''first_i, last_i, and first_j, first_j''' for the second index a~1 and b~2, with an increment incr_i and incr_j for each index. The min and max indices in the sereis are given by the tables '''[!MinIndex_i], [!MaxIndex_i], [!MinIndex_j], [!MaxIndex_j]'''. As an example, set first_i=50, last_i=100, incr_i=10, first_j=1, last_j=2, incr_j=1. Pressing '''[RUN]''', the function 'check_data_files' is activated and yields the list of file names, with the two last ones, c100a.png and c100b.png, marked as not found.

     13== aver_stat, simple field average ==
     14
    1015This function provides field average or global statistics on the whole input file series. Let us set first_i=1,last_i=99, incr_i=1. Then run 'aver_stat'. The average image is displayed and stored as Images.stat/c001ab.png.

     18== aver_stat, global statistics ==
    1319
    1420Other statistics can be obtained by aver_stat using a projection object. To create an object, go back to uvmat. Then check '''Projection object''' (tag = '''[!CheckObject]''') in series.

    16 = time_series =
     22
     23== time_series ==
    1724
    1825This function provides the image intensity at a set of points versus time. First define the set of points as a projection object, using uvmat.

    20 = data organisation =
     27== data organisation ==
     28
    2129Functions from series store results in files (except 'check_data_files'), so you need writing access on the data directory. An alternative possibility is to create a mirror directory using symbolic links so that the folders of the original images remains unperturbed.
