nctools

[jml@xxxxxxxxxxxxx (LACROIX Jean-Marc)]

Hi,
I'd like to use netcdf for our datas descriptions, so i got netcdf.tar.Z
from your server, and i'd like too use GMT software to visualise some 
results. But the problem is GMT need ".grd" files and i don't know
understand how to create these files from netcdf .
May be by the use of "nctools", i tried to get them from crusty.er.usgs.gov
as suggested by the paper of Harry L. Jenter and Richard P. Signell
but i can't reach this server. Could you help me ?
thank's in advance, JM Lacroix.
