    1 With 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'''.

    35This 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.

    1921Functions 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.
    20  To create  such a mirror, first open the images with the menu bar option '''Open campaign/browse...''' (instead of '''Open/browse...'''). Press the browser button '''SELECT''' when the camppaign .../UVMAT_DEMO_FILES appears in the upper window '''[titlebox]''' of the browser (then the list of subfolders appears in the main window '''[list]'''. This opens a new GUI '''browse_data'''. Each example folder is then considered as an 'Experiment', and their subfolders are '!DataSeries'.

    22 Then select an 'Experiment' and a '!DataSeries' to open by uvmat.
     25Then select an ''''Experiment'''' and a ''''!DataSeries'''' to open by uvmat.
