Re: [ferret_users] bug in ferret v6.842 in respect to previous versions ?



One line was missing

let new_ax=x[gx=sh, i=10:100]
define axis/x/unit=km/from_data new_axis=new_ax
define grid/x=new_axis/y=sh new_grid
let new_sh=sh[g=new_grid]
shade new_sh
save/clobber/file=test.nc new_sh

Sorry,
Martin

Hope this helps for the moment ....

Best,
Martin

Dear Ferret users,

I often use ferret for reducing the size of the my Netcdf files by keeping model outputs only on the interesting part of my model integration domain.

In attachment, there is a topography of the Greenland ice sheet at a resolution of 15 km x 15 km. With the new version of ferret, I can not more save my model variables in a netcdf by using a reduced grid:

        NOAA/PMEL TMAP
        FERRET v6.84
        Linux 2.6.32-279.14.1.el6.x86_64 32-bit - 12/18/12
        22-Apr-13 09:26



yes? use topo.nc ; save/file=foo.nc/i=10:100/clobber sh
 LISTing to file foo.nc
 **TMAP ERR: error in line definition
             file coords dont match variable coords on axis X10_100
LIST/FORMAT=CDF/file=foo.nc/i=10:100/clobber sh
Command file, command group, or REPEAT execution aborted

although it works with the previous Ferret versions:


        NOAA/PMEL TMAP
        FERRET v6.72
        Linux 2.6.32-131.12.1.el6.x86_64 32-bit - 09/13/11
        22-Apr-13 09:26



yes? use topo.nc ; save/file=foo.nc/i=10:100/clobber sh
 LISTing to file foo.nc

Do you have any suggestions for resolving this issue ?

Thanks in advance for your help,
Xavier
