    47 To get the vorticity field, 'vort' , and other spatial derivatives, you need to come back to the GUI''' series''' with images in '''[Input Files]''' and '''[Action]''' as 'civ_series'. In''' civ_input''', select the check boxes '''[FIX1] ''' and  '''[PATCH1] ''', validate the input with '''[OK]''', then press '''[RUN]''' in the GUI '''series'''. A question box appears to warn about the existence of the result file, answer '''[OK]''' to refresh it with the new data. Otherwise the results are stored in a new subdirectory with extension '.civ1', so the previous results are not erased (you can modify this extension by editing the boxe '''[!OutputDirExt]''' in the GUI '''series'''.

    4949This will produce an interpolated velocity field and their spatial derivatives in the same netcdf file.  After this operation vorticity can be visualized in the GUI  '''uvmat''', selecting the option 'vort' in the popup menu '''[!FieldName]'''.
