This sounds more like a GMT error than a netCDF error.  If you have
netCDF installed on your system, then you have the "ncdump" utility
program, that shows the structure and contents of netCDF files.  When
you invoke "ncdump" on the netCDF file you are trying to read, does it
work?  If it's not a netCDF file, ncdump will tell you, but if ncdump
works to display the file, then the problem is with GMT.  I'm sorry we
can't help with GMT or GRDINFO, but we don't know much about them.  If
you can isolate the problem as a netCDF problem, then we can help with
it.
