Hi Arlindo,<br>
<br>
GRADS uses the environment variable GAUDFT to determine the path to the<br>
udft file. You should be able to point GRADS to the correct file by<br>
changing GAUDFT to the proper path to your UDFT file.<br>
</blockquote><div><br>GAUDFT is used for the classic, transfer-file based UDFs. The dynamic extensions in v1.9.0-rc1 use the environment variable GAUDXT instead. Detais are here:<br><br> <a href="http://opengrads.org/wiki/index.php?title=User_Defined_Extensions">http://opengrads.org/wiki/index.php?title=User_Defined_Extensions</a><br>

If that's not it, perhaps you have a permission problem with your file. Try:<br>
<br>
chmod +r <your_file><br>
</blockquote><div><br>This is likely the problem. From the error message:<br><br>
Error opening user command definition table<br>
File name is: /usr/local/bin/gex/udxt<br>
Error opening user function definition table<br>
File name is: /usr/local/bin/gex/udxt<br><br>it appears that the file /usr/local/bin/gex/udxt either does not exist, or have the wrong permission.<br>As Steve suggests, try this:<br><br>chmod +x /usr/local/bin/gex/udxt<br>
<br>If this file does not exist or you do not have permission to issue the chmod above, ask your system administrator for help.<br><br> Arlindo<br><br><br></div></div><br clear="all"><br>-- <br>Arlindo da Silva<br><a href="mailto:dasilva@alum.mit.edu">dasilva@alum.mit.edu</a><br>
