% The function first reads the name of the input file from the edit boxes  of the GUI
% A second input file can be introduced for filed comparison
% It then reads the input file(s) with the appropriate function, read for
% images, read_civxdata.m for CIVx PIV data, nc2struct for other netcdf
% files.

%%%%%%%%%%%%%%    SCALARS: %%%%%%%%%%%%??%%%
% scalars are displayed either as an image or countour plot, either as a color of
% velocity vectors. The scalar values in the first case is represented by
% UvData.Field.A, and by UvData.Field.C in the second case. The corresponding set of X
% and Y coordinates are represented by UvData.Field.AX and UvData.Field.AY, and .X and
% .Y for C (the same as velocity vectors). If A is a nxxny matrix (scalar
% on a regtular grid), then .AX andf.AY contains only two elements, represneting the
% coordinates of the four image corners. The scalar name is represented by
% the strings .AName and/or .CName.
% If the scalar exists in an input open (image or scalar stored under its
% name in a netcdf open), it is directly read at the level of Field{1}or Field{2}.
% Else only its name AName is recorded in Field{i}, and its field is then calculated 
%by the fuction calc_scal after the coordinate transform or after projection on an edit_object
