Hi Abbas,<br><br>I can't help you with Lats4d, but I can recommend the climate data operators CDO for such netcdf-operations:<br><a href="https://code.zmaw.de/projects/cdo">https://code.zmaw.de/projects/cdo</a><br><br>
Alternatively, you could use NCO, the netcdf operators:<br><a href="http://nco.sourceforge.net/nco.html">http://nco.sourceforge.net/nco.html</a><br><br>Regrads,<br>Heiner<br><br><br><div class="gmail_quote">On Fri, Aug 27, 2010 at 7:30 AM, abbas mofidi <span dir="ltr"><<a href="mailto:abbasmofidi@yahoo.com">abbasmofidi@yahoo.com</a>></span> wrote:<br>

<div>Hi GrADS Users,<br><br>I want to use Lats4d to combine several Netcdf files to each other. Can anyone provide me an example that shows me how to combine several Netcdf files together. I looked at Lats4d page but I really don't know what I need to put in command line. I applied following command but it doesn't work. <br>
<br>lats4d -v -q -i /home/Data/APHRO_ME_050deg_V0902.1981 -j /APHRO_ME_050deg_V0902.1982 -j /APHRO_ME_050deg_V0902.1983 -ftype sdf -o /home/Data/APHRODIT -time 01jan1981 31dec1983 <br><br>I'm using OpenGrADS (2.0.a8.oga.1) on Linux machine. You can find in the follow data description.<br>
