Error using sub2ind: out of range subscript

Hi,

I am running a matlab gui and when I load the data (multitiff file) and display it in the axes I get the following error. I don't know how to proceed because the error doesn't appear every time I run the code. I tried to check which version of sub2ind maltab is using and it seems to use the correct version. Thank you in advance for your help.

I think you'll have to submit this to official support with the app that causes the error...

You could try setting a breakpoint on error in the callback and see what the indices are at the tme it does fail, but it likely won't be anything you can fix given it's in the base code.

Ok, thank you. I will try to submit it to official support.

Hi @BIANCA,

I faced a similar warning message and error while working on a project. This behaviour occured sporadically. It turned out to be a graphics issue. Running the following command in the MATLAB command window before running the project fixed the issue for me:

>> opengl software

The above approach could help resolve the issue in your case as well. For more information on 'opengl', please refer to the following documentation:

I hope this helps!
