<p class="ecxMsoNormal" style="margin-bottom:12.0pt">Hi Deniz,<br>
<br>
when you write recognized "sdfopen" or "xdfopen", do you
mean that grads does not know the command? Is your grads-version compiled with
netcdf-support?<br>
<br>
It is certainly a good thing to create netcdf-files, as they are
self-descriptive. But still you could write binary data from matlab with the
command fwrite:<br>
<a href="http://www.mathworks.com/help/techdoc/ref/fwrite.html" target="_blank">http://www.mathworks.com/help/techdoc/ref/fwrite.html</a><br>
<br>
Then you have to follow the logic of grads binary files, ie. first longitude,
then latitude, then height, then time, as described in the manual.<br>
<br>
So far,<br>
Heiner</p>

<p class="ecxMsoNormal" style="margin-bottom:12.0pt">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</p>
