Brian,

In the radmap README file the command line usage is 

       radmap -(n|r|s|v|t|m|c) nids_file gif_file title_string [plot_area]

where plot_area must be specified for -n,-r,-t, and -c:

      "The plot area in the form (lat_ll, lon_ll, lat_ur, lon_ur)
       defining the lower-left and upper-right coordinates (e.g. 
39.6;-126.1;49.8;-109.9).
       When making a thumbnail (-t) of a single-site data, specify plot_area as 
the
       phrase "DSET".

so your radmap command should be formatted as:

radmap -r /usr/local/.../NCR_20090408_0029 /data1/ldm/.../junk2.gif "title" 
"lat_ll; lon_ll; lat_ur; lon_ur"

As for products like TR0, radmap is unable to read them correctly at this time 
but I'll look into adding support.

Best,
