5%
6% OUTPUT:
7% GetFieldData: structure containing the information on the selected
8%      fields, obtained by applying the fct red_GUI to the GUI get_field
9%   .FieldOption='vectors': variables are used for vector plot
10%                  'scalar': variables are used for scalar plot,
11%                  '1Dplot': variables are used for usual x-y plot,
12%                  'civdata...': go back to automatic reading of civ data
13%   .PanelVectors: sub-structure variables used as vector components
14%   .PanelScalar:
15% INPUT:
16% FileName: name (including path) of the netcdf file to open
17% ParmIn: structure containing parameters for preselecting menus:
18%   .Title: set the title of the GUI get_field
19%   .SwitchVarIndexTime='file index','variable' or 'matrix index': select the default option for 'time'
20%   .TimeAttrName: preselect the name of a global attribute for time
21%   .SeriesInput=1 if get_field is called by the GUI series,=0 otherwise (plot options provided in the latter case)
22%   .Coord_x,.Coord_y,.Coord_z, names of the variables used as the three coordinates
23%   .scalar : set the default choise of the scale variable
24%   .vector_x, .vector_y : set the default choise for the variables used for the x and y vector components
