error while plotting fixation/heatmap.

i need to plot fixationmap/heatmap and need to find AOI/ROI from eye gaze data for a project . I was implementing gazealyse toolbox with the sample data provided with downloaded file to get an idea of the software .i am currently running it on MATLAb 2013a as i was getting 'bufsize' 'textscan' error with the latest version.

i am getting several errors of the nature

reference to non-existent field ' '

when i try ro run different funtions.

for example

Reference to non-existent field 'white'.

Error in GA_gui_plot>GA_gui_plot_OpeningFcn (line 74)

set(handles.cb_white,'Value',plot.white);

Error in gui_mainfcn (line 221)

feval(gui_State.gui_OpeningFcn, gui_hFigure, [], guidata(gui_hFigure), varargin{:});

Error in GA_gui_plot (line 42)

gui_mainfcn(gui_State, varargin{:});

Error in GA_gui_main>Menu7_1_Plot_Callback (line 1009)

GA_gui_plot(handles.GA_mainWin);

Error in gui_mainfcn (line 96)

feval(varargin{:});

Error in GA_gui_main (line 42)

gui_mainfcn(gui_State, varargin{:});

Error in @(hObject,eventdata)GA_gui_main('Menu7_1_Plot_Callback',hObject,eventdata,guidata(hObject))

Error while evaluating uimenu Callback

this happenes when i try to select plot setting.

another error i get is

Error using textscan

Invalid file identifier. Use fopen to generate a valid file identifier.

Error in GA_heatmap>generate_heatmaps (line 196)

series = textscan(fid, '%s', 'delimiter' ,'\n');

Error in GA_heatmap (line 84)

generate_heatmaps(heat,eye);

Error in GA_controler (line 605)

GA_heatmap();

Error in GA_gui_main>Menu11_4_HM_run_Callback (line 1161)

GA_controler('heatmaps',handles.data.eye)

Error in gui_mainfcn (line 96)

feval(varargin{:});

Error in GA_gui_main (line 42)

gui_mainfcn(gui_State, varargin{:});

Error in @(hObject,eventdata)GA_gui_main('Menu11_4_HM_run_Callback',hObject,eventdata,guidata(hObject))

Error while evaluating uimenu Callback

when i try to run generate heatmap option

If anybody has implemented gazealyse before or knows what is the problem please do help.

thank you for your help

Can you upload your .m file? R2013a is at least 8 years old and may have a bug. I can veirfy that and suggest you a work around.
