Well, i've trying.
'd oTCDChcl'
everything is ok for me.
Maybe you creating subset by ftp2u, or g2sub and not create new ctl
and idx files?:

perl g2ctl -verf gfs.$1z.pgrb2f%f2 > gfs_$1z.ctl
/home/pdjakow/GrADS/bin/gribmap -i gfs_$1z.ctl

where $1 is t00,t06,t12 or t18. For GRIB1 files use grib2ctl.pl
instead of g2ctl.
