Chris,

Your $RAD environmental variable should be $GEMDATA/nexrad.

Your $GEMTBL/config/datatype.tbl file has a template for NEXRIII:
NEXRIII      $RAD/NIDS/%SITE%/%PROD%   %PROD%_YYYYMMDD_HHNN

Eg, $RAD in the above gets replaced by $GEMDATA/nexrad.

Your files must be named N0R_YYYYMMDD_HHNN,

In your previoud message, you showed that you named you file:
NOR__200512301800
That is incorrect. It must be N0R_20051230_1800
Also note, that is supposed to be a "zero" bewteen N and R in N0R).

Also note, in general, you cannot mix the Gemenviron file from an older release
since table locations, etc change with time.
