The specific error in your email is happening because Grads is not successfully opening the first file. You can't specify the index of the file to be opened. The rule is that the first file that is successfully opened gets the index value 1, the second that is opened (when another file is already open) is given index 2, and so on. If your intended file "1" does not open, then if the second intended file opens, it is given the index value 1. So your first point of troubleshooting should be to determine why the file TES_hdf.ctl is not opening the data file in it. The control file you attached to this email does not have the same file name as that in the script, so that could be the problem.<br>
<br>Let me know if this continues after checking on that issue.<br><br>Jeff Duda<br><br><br><div class="gmail_quote">On Tue, Nov 27, 2012 at 3:03 PM, Jonathan Wynn Smith <span dir="ltr"><<a href="mailto:jwynnsmith.help@gmail.com" target="_blank">jwynnsmith.help@gmail.com</a>></span> wrote:<br>
