Chance,
If the program is not locating the data, be sure the
NEXRIII template in $GEMTBL/config/datatype.tbl
matches the file naming you are using at your site.
Then, verify that your data dirrectories are current
eg, look in $RAD/NIDS/AMA/N0R etc and make sure that the
file times are within the 30 minute RADDUR window,
or increate the window.
