Hi Deniz,<br><br>you don't nead a ctl-file to open a netcdf-file in grads. If your file follows the COARDS-standard, then you can open it with 'sdfopen <a href="http://ures.nc" target="_blank">ures.nc</a>'. If grads won't recognise it, you might want to try an older grads-version. We had some problems here with grads 2.0 and netcdf.<br>
<br>If grads still won't open your file, you can write a ctl-file and try to open that with the command 'xdfopen'. The ctl-file looks a bit different from standard ctl-files, look here:<br><a href="http://www.iges.org/grads/gadoc/gradcomdxdfopen.html" target="_blank">http://www.iges.org/grads/gadoc/gradcomdxdfopen.html</a><br>
<br>Then, you would need the output from ncdump in order to know what is inside the netcdf-file. Alternatively you can use the climate data operators (CDO) with the command "cdo sinfo <a href="http://ures.nc" target="_blank">ures.nc</a>".<br>
Or in matlab, if you have the mexnc-package installed, you read the information with <br>info=nc_info('<a href="http://ures.nc" target="_blank">ures.nc</a>')<br>Then you can access all details in info.<br><br>Finally, if it is only you who will use the data, it might be simpler to write binary output in matlab and use a standard ctl.<br>
<br>Kind regards from Stockholm,<br>Heiner<br><br></p><div><p class="MsoNormal">On Mon, Nov 8, 2010 at 10:11 AM, Deniz Demirhan Bari <<a href="mailto:bari@iap-kborn.de" target="_blank">bari@iap-kborn.de</a>> wrote:</p>
