This may be a simple question, though I am having trouble finding which file is the main file and opening the gui. I used the openpivgui.m file installing as a Matlab app, and it opens the gui but the gui displays an error attempting to load files. I can post the error messages here Reference to non-existent field 'edit_path'. Error in readImDir>update_gui (line 256) set(handles.edit_path,'String',handles.path); Error in readImDir>readImDir_OpeningFcn (line 53) update_gui(hObject,[],handles); Error in gui_mainfcn (line 220) feval(gui_State.gui_OpeningFcn, gui_hFigure, [], guidata(gui_hFigure), varargin{:}); Error in readImDir (line 18) [varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:}); Error in openpivgui>load_Callback (line 380) [handles.files,handles.path] = readImDir; Error in gui_mainfcn (line 95) feval(varargin{:}); Error in openpivgui (line 42) gui_mainfcn(gui_State, varargin{:}); Error in matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)openpivgui('load_Callback',hObject,eventdata,guidata(hObject)) Error while evaluating Menu Callback.

Please post here which Matlab version you're using. It seems that the problem is that you have a newer version that GUI was developed for. You can notice here 

https://github.com/OpenPIV/openpiv-matlab/tree/master

that the GUI was created quite few years ago. We'd be glad if someone with a newer version can help us to port the GUI to a new version, but we do not have the time for it right now. 

Would you consider a command line type of a tool? the Python version is much more developed for instance.
