<p>Hi Abdalmajeid,</p>
<p><br>
</p>
<p>Welcome to GATE!</p>
<p><br>
</p>
<p>The error message looks like something that has nothing to do with materials, but rather with the image format that you would like to read from or write to.</p>
<p><br>
</p>
<p>Could you send us the actual macro file that is giving you this error?</p>
