    38 For further data processing it can be convenient to merge all fields in a single netcdf file. This can be done by opening the previous results in series and applying the [Action] function 'time_series'. A projection object is needed at this stage, so create a '''[Projection object/points]''' in the image. Select '''[ProjMode]'''= 'projection' with a range=200. Now when selecting '''[Projection Object]''' the point created should appear. Then '''[RUN]''' the calculation.

    4040The result is obtained as a single netcdf file 'images.civ.mproj.tseries/Pike_000001-000020.nc'. Opening this file with '''uvmat''', Observe the curve displacement U (and V) versus time. With the GUI '''get_field''' which pops up, it is also possible to show the rotation or divergence in the figure.
