I recieve this error but the code keeps running:

Invalid or deleted object.
Error in matlab.graphics.controls.internal.ToolTipMixin/showToolTip
Error in matlab.graphics.controls.ToolbarController/showToolTip
Error in matlab.graphics.controls.ToolbarController>@(e,d)obj.showToolTip(btn)
Error in print (line 36)
drawnow; % give changes a chance to be processed
Error in saveas (line 181)
        print( h, name, ['-d' dev{i}] )
Error in AllCesCalculator_20200615>sion_finder (line 334)
    saveas(number_of_figures(i),fullfile(sion_path,[ number_of_figures(i).Name '.tif']));
Error in sion_AllCesCalculator_20200615>TUpdaterForsion (line 74)
          =sion_finder(X,Y,more_smooth_gaussian,less_smooth_gaussian,thresh,ce_name,r_equivalent_pxl,sion_path);
Error in sion_AllCesCalculator_20200615 (line 52)
 TUpdaterForsion(T,p_length,nfiles,save_image_path,sion_path,fullFileNameofxy,fullFileNameofsizexy,images_loc,ce_names_c) 

Any idea?

Most probably, the handle number_of_figures(i) belongs to a deleted figure.

Hey Zeynab,

Since you haven't shared the code with us, I guess the main reason why you're getting the error is because of a referencing issue when trying to modify something incorrectly within your code. You're probably trying to access or delete something that's already deleted.

A solution to this could be to save the handles (depending on your application) and then use the 'hold on' functionality to preserve the handle.

You could also go through this MATLAB Answer to get more info.

Hope this helps!
