Mark,<br><br> Please download g2gdf/g2ctl, .pl and .exe versions, from:<br><br> <a href="http://opengrads.org/devel/win32/">http://opengrads.org/devel/win32/</a><br><br> Then grab a gfs forecast, say<br><br> <a href="ftp://ftpprd.ncep.noaa.gov/pub/data/nccf/com/gfs/prod/gfs.2008041512/gfs.t12z.pgrb2bf06">ftp://ftpprd.ncep.noaa.gov/pub/data/nccf/com/gfs/prod/gfs.2008041512/gfs.t12z.pgrb2bf06</a><br>
<br>and try this (.exe version):<br><br>g2gdf -verf gfs.t12z.pgrb2bf06<br><br> I'd expect the attached .gdf/.inv files to be produced. Start grads and type<br><br>ga-> g2_open gfs.t12z.pgrb2bf06.gdf<br>ga-> set lev 825<br>
ga-> d g2(tmpprs)<br><br> Does it work for you? The plot is attached. I tried this with Strawberry perl, another native Win32 build:<br><br> <a href="http://strawberryperl.com/">http://strawberryperl.com/</a><br><br>
The same should work with ActiveState perl. Let me know if it doesn't, and I'll install it and give it a try. However, the .exe files were created with Strawberry perl and should work as is --- no need for perl to be installed on your machine at all.<br>
