<p>Hi Jean-Michel,</p>
<p><br>
</p>
<p>Previously I have contacted the "graham" staff, their response was everything seemed normal on their ends. Thats why I am here to see if I can have any luck.</p>
<p>A few more of my runs have died, and I have not received any reply from them yet.</p>

<br>
I could be be due to disk system on this computer that was not allowing the model
<br>
to access this file from one othe node you were using. To check this, I would suggest
<br>
to try to re-run it without changing anything, and keep a reccord of which node your<br>
job was affected to. This way you might be able to contact the "graham" admin staff<br>
with more precise information.<br>
<br>
Cheers,<br>
