Dana,

NMAP is expecting the data in the satellite and radar directories to end with 
the _YYYYMMDD_HHNN string:
This is in $GEMPAK/source/programs/gui/nmap2/nmap_image.c routine:
image_getFileTm()

The program creates the GEMPAK time YYMMDD/HHNN from that string, so it is
not flexible on the naming conventions.  Without the _ character and the
extension .8wv that you have, the interpretation of the time will be
messed up.

Since GOES images can be 4x per hour normally, and 8x per hour in RSO mode,
your naming convention should allow for that. If necessary, you can create 
symbolic links from file names to the alternate convention.
