It is possible to create control files for each data file, but I don't see why you would ever want to do that.� It would be much easier and take much less time to change the DSET entry in your one control file instead.� For the templating, you only have to match up the pattern of the data file name.� See <a href="http://www.iges.org/grads/gadoc/templates.html">this page about templates</a> for more information.� THe warning is just a warning.� The only reason it appears is because you have the keyword "options template" in your control file, yet you have no template symbols in the DSET entry of your control file.� Change your DSET line to this: DSET %y4/mld%y4%m2%d2.gpv to be able to use the one control file to open all data files.� Again, make sure you run this from the directory that contains those directories or else you will get errors from the control file being unable to find the data.<br>
<br>The message you will get when Grads successfully displays data is something like what you said: Contouring: 50 to 450 interval 50<br>Possible reasons for why you couldn't see it:<br>1) Did you open a display window?<br>
2) Is your data defined over a different geographical region than the one specified in the control file?� If the dimension environment completely misses the region over which the data are defined, you won't see anything even though Grads will display it.<br>
<br>You said someone else made these files.� I suggest talking to them about how they made them to determine how to display the data if you continue to have problems.<br><br>Jeff<br><br><div class="gmail_quote">On Mon, Jul 30, 2012 at 11:40 PM, irene alabia <span dir="ltr"><<a href="mailto:irenealabia@gmail.com" target="_blank">irenealabia@gmail.com</a>></span> wrote:<br>
