    11With uvmat, open the example UVMAT_DEMO_FILES/EX06_PIV_challenge_2005_CaseC (representing a jet seeded by particles). We notice that the series contains 60 image pairs, labelled by a number with 3 digits and a letter index a and b. The nomenclature type '''[!NomType]''', given as the first image index, is therefore '001a'. Activate the menu bar option '''Run/field series''' to open the new GUI '''series'''.

    3 This GUI is used to launch various processing programs on field series. The program name is selected in the menu '''[ActionName]'''. The default option 'check_data_files' just list the set of input files and checks their existence and type.

    5 The 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.

     7= aver_stat, simple field average =
     8This 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.

     10= aver_stat, global statistics =
     11
     12Other 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.

     14= time_series =
     15
     16This function provides the image intensity at a set of points versus time. First define the set of points as a projection object, using uvmat.
