Re: [ferret_users] descriptor file

[Russ Fiedler <russell.fiedler@xxxxxxxx>]

Hi Raffa,

You could use Andrew Wittenberg's perl script to construct a descriptor
file.

http://www.gfdl.noaa.gov/~atw/ferret/make_des


Each stepfile record only contains 1 file so it's a bit bigger

make_des  1stgroup_file.nc.??? 2ndgroup_file.nc.??? >! timeseries.des

should do the trick.
