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.

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.

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.
