[ferret_users] big file issue?



Hello,

 

I was wondering whether I hit some kind of limit with the data file below.

Any suggestions welcome!

 

Thank you very much,

Cheers,

Joerg

 

So this is my file – 3.7 Gb to save you the counting

-r-------- 1 jk61  nfsnobody 3733003888 Nov 12 16:31 hwsd1.21type.nc

 

[jk61@alice01 HWSD1.21]$ ncdump -h hwsd1.21type.nc

netcdf hwsd1.21type {

dimensions:

                Longitude = 43200 ;

                Latitude = 21600 ;

variables:

                double Longitude(Longitude) ;

                                Longitude:Units = "DegreeE" ;

                double Latitude(Latitude) ;

                                Latitude:Units = "DegreeN" ;

                int Soiltype(Latitude, Longitude) ;

}

 

I am using

                FERRET v6.84  

                Linux 2.6.32-358.11.1.el6.x86_64 64-bit - 09/05/13

 

yes? use hwsd1.21type.nc

yes? show data

     currently SET data sets:

    1> ./hwsd1.21type.nc  (default)

name     title                             I         J         K         L         M         N

SOILTYPE                                  1:43200   1:21600   ...       ...   

 

yes? shade SOILTYPE[x=-180:180]

gives me the output below

 

However

shade SOILTYPE[x=0:180]

 

results in
