    1111== Synthetic Images ==
    12 In the folder '!AnalyticFlows', select one of the images from the 'a3b' series. It shows a diagonal uniform flow running from the bottom left corner to the top right one. '''[RUN]''' a PIV on the images series only using '''[CIV1]''', '''[FIX1]''' and '''[PATCH1]''' with the default parameters.
     12In the folder 'UVMAT_DEMO08_deformation', select one of the images from the 'a3b' series. It shows a diagonal uniform flow running from the bottom left corner to the top right one. '''[RUN]''' a PIV on the images series only using '''[CIV1]''', '''[FIX1]''' and '''[PATCH1]''' with the default parameters.
    1313Then '''[Open]''' one of the vector files (.civ) created. We need to substract the numerical solution to this image in order to keep only the errors between our calculation and the theorical one. Select the mall red square'''[!SubField]''' under the '''[Input]''' table to open a second file in '''uvmat'''. Open the netcdf file of the synthetic solution 'a3b_sol_num.nc'. The GUI '''get_field''' pops up, select 'vectors' in the '''[!FieldOptions]''' table and 'U' and 'V' in the right and left tables under '''[Ordinate]'''. The '''[Coordinates]''' should still remain as 'X' and 'Y'. Click on '''[OK]'''. An 'ERROR' window pops up, select '''[OK]''' and close the GUI '''set_object]''' which automatically popped up.

    4646== Adding an increment 'dt' in the PIV ==
    47 In the folder '!AnalyticFlows', select one of the images from the 'a2b' series. It shows a Lamb-Oseen vortex flow. In this part we are going to using the '''deformation''' CIV2 function and observe its effect on the calculations. To beginning with '''[RUN]''' a PIV on the images series only using '''[CIV2]''', '''[FIX2]''' and '''[PATCH2]''' with the default parameters.
