I have netcdf file containing daily sst data over a year, and I need to extract the grid data over an irregular area for each day, so I used the maskout function.<br><br>First I created a shapefile for the area that I needed using ArcGis software (1.png).<br><br>Then I followed the instructions posted in a previous thread by Dr. Yaqiang Wang (<a href="http://gradsusr.org/pipermail/gradsusr/2013-April/034603.html">http://gradsusr.org/pipermail/gradsusr/2013-April/034603.html</a>). So using MeteoInfo software I made a grads maskout data with the shapefile (2.png), and I changed the TDEF in the maskout ctl file just as stated (3.png).<br><br>The maskout works fine for the first day (t=1) of the data (4.png), but the problem is that when I try to use another 't' different than 1 it gives an error (5.png).<br><br>I hope you could give some ideas of what the error might be. Is it a mistake of how to create the shapefile, or an error in the control file?<br><br>Looking forward for your help. Thanks in advance.<br><br>Alejandro.<br><br><div id="inlineImage0" style="display: inline-block; "><span applecontenteditable="true"> </span><span applecontenteditable="true"> </span></div><em><font color="#ff0000" face="Garamond, Times, Serif " size="4"></font></em></div><span><1.png></span><span><2.png></span><span><3.png></span><span><4.png></span><span><5.png></span>_______________________________________________<br>gradsusr mailing list<br><a href="mailto:gradsusr@gradsusr.org">gradsusr@gradsusr.org</a><br><a href="http://gradsusr.org/mailman/listinfo/gradsusr">http://gradsusr.org/mailman/listinfo/gradsusr</a><br></div></span></blockquote></div><br><div>
