Bill, The file templates are described at: http://www.unidata.ucar.edu/packages/gempak/tutorial/filetemplates.html See the file: $GEMTBL/config/datatype.tbl The environmental variables for GEMDATA, MODEL, SAT and RAD which you will need set are deined in $NAWIPS/Gemenviron. Asside from being used in NMAP and NMAP2, these templated can be used in GEMPAK programs. For example, using GDFILE=eta in a grid program will use the template defined in the datatype.tbl file mentioned above to determine the latest available ETA 211 run to use.
