It seems that the files should not be joined together.

Subject: [gradsusr] Cannot Contour Grid - all undefined values error
Hi,

I have what would seem to be a very simple data-set and "variable" I'm trying to plot wiht GrADS.  

The grib files are located here...

ftp://ftp.cdc.noaa.gov/Public/gbates/reforecast2/efi_grib2/pctile.2017060500.000_to_024hrs.grib2

I am simply downloading several of these files, then do this:

cat * > efi.master
g2ctl efi.master > efi.master.ctl
gribmap -i efi.master.ctl

I'm simply trying to plot either:

temp2m
wind10m
apcpsfc

When I try to display the data, I get the error: 

Cannot Contour Grid - all undefined values

Thanks for any help....

Bill
