Meng Wu,

I believe that you mean you are using the LDM to ingest the Unidata-Wisconsin
datastream (LDM feed type MCIDAS).  If you mean something else, please let
me know.

Can you give me an example of exactly what you are trying to do?  This
would include the McIDAS commands and a listing of the header from the
image (AREA file).

When I understand what you have tried and the problems you have run into,
I can, hopefully, provide the appropriate McIDAS commands to accomplish
your goal.

>Thank you very much!!
