Is this the post you're referring to?<br>

<br>
It's always best to refer directly to the thread you read.<br>
<br>
What version of Gromacs are you using? I seem to recall that the quoted error<br>
came up in 3.3.3, but not in the 4.0.x series. I never actually solved the<br>
above problem; my issue was with version 4.0.2, and it ended up being my own<br>
fault for using an improper command :)<br>
