Hi Baraa can you post the model you are using? Also what version of MATLAB are you using?

Hi @Nishan Nekoo

I think the model is available here:

This error is due to changes in the behavior of masks since this model was created in MATLAB R2009b. Please right click on the mask, select Edit Mask and on the Code tab, change the line of code to the above line. That should resolve the error you are seeing.
