[gradsusr] Lats4d!

[abbas mofidi]

Hi GrADS Users,

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. 


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 


I'm using OpenGrADS (2.0.a8.oga.1) on Linux machine. You can find in the follow 
data description.

Thanks,
Abbas
