<p><font color="#000099">We were able to resolve this off the
mailing list. My understanding is that they installed XCrySDen
as root and were trying to use XCrySDen in a user account were
they didn't have executable permission for str2xcr.</font></p>
<p><font color="#000099">It took us a bit to figure this out because
I usually install XCrySDen [3] in the user account (and not as
root).</font><br>

<p>Could you paste the specific error message here and perhaps
attach the structure file that causes problems for you, to see
if the issue can be reproduced. Without knowing the specifics it
is difficult to say what went wrong,</p>
