Glenn,
Ntrans displays cgm format meta files (eg lists of drawing commands)
that can be produced from Gempak plotting programs like gdcntr, gdwind,
gdplot etc using the nc meta file driver.
Ntrans does not read data management files as you are attempting.
Instead, you can use gdcntr for example with the xw driver to display
data from the data management fioles that the decoders produce
sending the display to your X window. Or, use the gui Garp.
Mnay people use the nc meta file driver with programs run from crontabs
to produce ready canned metafiles for map discussions etc. with ntrans.
More information on ntrans can be found in our tutorial at:
