<DIV><FONT face=Arial size=2>Hi,<BR><BR>When using partial (or sometimes
with the whole file GRIBS1 dowloaded) downloads of GFS GRIBS1 files to plot
variables in PC GRADS (I'm running on Win XP SP2), I often receive the message
"Cannot contour grid - all undefined values " when I try to generate the plot.
However, sometimes, for no obvious reason the process works and the plot is
successfully generated.</FONT></DIV>

<DIV><FONT face=Arial size=2>To partially download files I am using the scripts
provided by Wesley Ebisuzaki, and these are working without problem. Once
downloaded I run grib2ctl.pl to create the ctl file, and this works ok. I then
run gribmap on the ctl file and this also seems ok.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Any ideas on what is causing my
problems?</FONT></DIV>
