Hello, Everyone,<br>
<br>
When I tried to test the eof example at<br>
<a href="http://opengrads.org/wiki/index.php?title=PyGrADS_Interactive_Shell" target="_blank">http://opengrads.org/wiki/index.php?title=PyGrADS_Interactive_Shell</a><br>
<br>
There was an error said I cannot open the netcdf file.<br>
<br>
Can anybody tell my how to solve this problem?<br>
<br></blockquote><div><br></div><div>Strange, it almost looks like you are loading the wrong version of udunits. Try starting the regular grads and openbing this file:</div><div><br></div><div>% grads</div><div>...</div>
<div>ga-> sdfopen <a href="http://slp_djf.nc">slp_djf.nc</a></div><div><br></div><div>and see if you have the same error message. Also, find the grads binary you are using</div><div><br></div><div>% which grads</div><div>
