Hi, Annibale,
<div>You need to add a command to close the file at the end of your script:</div>
<div> rc=close(outfile)</div>
<div><br>
</div>
<div>If you add this to the script fragment in your Case #1, it will create a file that contains only one line: “LON LAT PREC”</div>
<div><br>
</div>
<div>If you want to write out the data, as well as the 1-line header, then take a look at examples under the heading ‘Output gridded data in ascii format” on this page: <a href="http://cola.gmu.edu/grads/gadoc/ascii.html">http://cola.gmu.edu/grads/gadoc/ascii.html</a></div>

<div dir="ltr">Dear GRADS Users,
<div><br>
</div>
<div>I'm trying to use the "write" intrinsic function to write on a file (.txt or dat) the daily mean precipitation for every day derived from a precipitation dataset (e.g. 2013 CMORPH daily precipitation estimates, see below).</div>
<div>At this stage, I'm just trying to create the output file, which is a result I'm not able to get yet.</div>
<div>I don't know for which reason, this function in one case works and in another doesn't.</div>
<div> </div>
<div><b>Case 1</b>: I can run the script with no errors but the .txt file is not generated within the defined current directory.</div>
<div><br>
</div>
<div>
<div>'sdfopen <a href="http://iridl.ldeo.columbia.edu/SOURCES/.NOAA/.NCEP/.CPC/.CMORPH/.daily/.mean/.morphed/.cmorph/T/%2801%20Jan%202013%29%2831%20Dec%202013%29RANGEEDGES/dods">

<div>outfile='C:/OpenGrADS/Contents/Resources/SampleDatasets/CMORPH.txt'</div>
<div>'set gxout print'</div>
<div>'set prnopts %0.3f 5 1'</div>
<div>rc=write(outfile, 'LON LAT PREC')</div>
</div>
<div><br>
</div>
<div><b>Case 2</b>: Take an example I found on the web and in this case I can actually get the NCEP.txt file in my current directory.</div>
<div><br>
</div>
<div>'sdfopen <a href="http://monsoondata.org:9090/dods/rean2d">http://monsoondata.org:9090/dods/rean2d</a>'</div>
<div>outfile='C:/OpenGrADS/Contents/Resources/SampleDatasets/NCEP.txt'</div>
<div>'set gxout print'</div>
<div>'set prnopts %6.2f 5 1'</div>
<div>rc=write(outfile, 'LON LAT PREC') </div>
<div><br>
</div>
<div>The first example is related to a precipitation dataset which I'm interested into, the second is an excerpt from a script I found on the web.</div>
<div><br>
</div>
<div>Could explain me why this happens?</div>
<div>Could you also provide me with some tested working scripts, which use this function within a while loop (which is what I would need to extract the mean daily precipitation from a given dataset)?</div>
<div><br>
</div>
<div>Thank you very much!</div>
<div><br>
</div>
<div>Kindest regards</div>
