It looks to me as if your .fig file no longer holds a graphics structure. It might be corrupted, and you might have to restore it.

yes that is exactly what happened.

I was obliged to return to a backuped file to be able to reopen the figure file

Use the debugger to find the reason of the problem. Type this in the command window:

dbstop if error

Then run the code again. When Matlab stops, check the types of the variables:

hgDataVars
hgDataVars.(vars_hgM{1})
hgDataVars.(vars_hgM{1}).GraphicsObjects
hgDataVars.(vars_hgM{1}).GraphicsObjects.Format3Data;

[mohammad ibrahim]

thank you for your answer

actually the problem comes from here

hgDataVars.(vars_hgM{1}).GraphicsObjects

ans = [ ]

this GraphicsObjects should be the figure

[Jan]

Okay. Now you know, where to search for the problem. Open the soure in the editor and search, where GraphicsObjects is set to the empty matrix.

Try clearing your workspace and then launching the GUI. Looks like you have a variable with the same name as the GUI.

I did but the same error appears
