Thread Subject: big bug with GUIDE

Hi,

I work with matlab R2008a, and I have encountered serious problem when I have tried to create a GUI using GUIDE.

Today, it is the third time that I got the following error:

?? Error using ==> hgload at 53
invalid Figure file format

Error in ==> openfig at 72
    [fig, savedvisible] = hgload(filename, struct('Visible','off'));

Error in ==> gui_mainfcn>local_openfig at 286
    gui_hFigure = openfig(name, singleton, visible);

Error in ==> gui_mainfcn at 159
        gui_hFigure = local_openfig(gui_State.gui_Name, gui_SingletonOpt, gui_Visible);

Error in ==> Mike_Viewer3D_2 at 42
    gui_mainfcn(gui_State, varargin{:});

Each time, this error occur after matlab has crashed. Each time the ".fig" file could not be opened again and I had to start writing again the GUI from the beginning.
I am really frustrated and I do not know what to do.

I really need help,
Is there a way to recover, or at least open the corrupted ".fig" file in order to try to correct it?

Thank you in advance
 Mike

I cannot help with what might very well be a bug, but I suggest you try writing your GUI without GUIDE. Problems like this are what persuaded me to stop using GUIDE. For an example of a GUI that doesn't use GUIDE (and isn't that hard to make!) see this:

Hi.

Mike, have you found any way of recovering the fig file? I had a rather detailed GUI and would prefer not to have to build it all over again!
Does anyone know if we can manually edit anything in the file to fix it?

Thanks,
cspsp.

it appears that at least in 7.0.4.365(r14) the fig file is really a mat file with a structure in it that has the uicontrols and other info. try copying it and rename to .mat and see if it will load. not sure what you could fix if it won't load, but if it does maybe you could find a bad control or something and delete just that one to recover.

There is a bug report on this issue:
http://www.mathworks.com/support/bugreports/details.html?rp=452282
Its is fixed in 8b. In 8a you need to download a patch for guidemfile.m from the above URL link.

I think under similar circumstances, I would adopt a strategy of taking backups
so that it would not be necessary to start over from the beginning.

I've had the same issue on 2008a. The downloaded patched guide refuses
to open .FIG file. In fact all other matlab GUIs cause errors in the
command window after the attempt. Does anybody know how to fix the FIG
file?

Ok. I've tried something that was a long shot and it worked:
1. Rename File.FIG into File.MAT
2. Load it to the workspace (drag'n'drop).
3. Delete field hgS_070000.properties.WindowButtonDownFcn, which (I
suspected) contain incorrect reference to automatic function handle.
4. Then: >> save File.mat hgS_070000
5. Rename File.MAT into File.FIG.
That's it! I can't believe I am saying it, but MathWorks has screwed
up this time.

-Sergiy

There's no need to rename the file, just use the -mat flag when using load

>> load -mat myFigFile.fig
>> % edit the structure
>> save -mat myFigFile.fig

i guess my idea wasn't that far off after all.

Hi Phil and others,
       I am using Matlab 2008a and the GUI developed keeps getting corrupt. When I try to load using the command prompt nothing happens. If I rename to .mat and drop it in editor I see this:
MATLAB 5.0 MAT-file, Platform: PCWIN, Created on: Tue Aug 11 19:01:48 2009

Any suggestions ?

"Nothing" is less than I'd expect.
If you "load" the file, the contents is imported as variables in the work spaces. So "whos" should show you the imported data.
It is less confusing to import the data to a variable:
  FigData = load('myFigFile.fig', '-mat')

Good luck, Jan

A .fig file contains only one variable and it is already a structure, plus the name of the variable is the same as the one that needs to be used when saving the altered structure back into a .fig file, so I don't believe using the functional form of load gains anything.

On the saving end you do need to be careful in that the command I give will save all variables when in fact you only want to save the (altered) one that came from the .fig file.

Dera Phil Goddard!

Naresh Pai said, that "nothing happens" after loading. This is obviously impossible, but the effects of LOAD are "not visible" without further knowledge.
You are right, the functional form does not "gain" anything, but at least Naresh Pai knows, where to look for the loaded data!

Good luck, Jan

Phil and Jan,
   Thanks for your responses. I had to ultimately rebuild my GUI. Fortunately, I had a backed-up version, so did not have to start from scratch.

Naresh

Hello All,
      I also experienced the same problem with corrupt GUI (line 53, hgload ... etc.). I had to rebuild the GUI. This is an accepted bug & available in Matlab buglist. However, the workaround mentioned there did not help.
      I was viewing the application from GUIDE using 'Run Figure' command of GUIDE and was also simultaneouls trying to run the application that invoked the GUI. Now I close save & close the GUI before running the application. The GUI did not get corrupted again. So, may be that, running the same GUI from GUIDE & in the application simultaneously is the cause.
      I am not sure how far my guess is true. Does anybody have any similar experience?
Rgds,
Saurav
