Good evening everyone, In an attempt to open up a grib2 file, I have downloaded and unpacked the wgrib2 tar file and copied the g2ctl script onto a text edit file. When I type in the command 'run g2ctl gfs_4_20140112_1200_009.grb2' I get the prompt, "error opening script file: g2ctl". Any thoughts on why this would be? Ethan
