Frederic,

That is correct.

I don't know of one, but it would probably be better to
ask other McIDAS users if they have developed one.  The
best way to do this is post your query to the mcidas-x 
email list that we maintain (I see that you are already
subscribed to this list, so you should have no problems
in posting).  There are a number of SSEC folks on this
list, and they may know of someone that has developed
the application you are looking for.

>Thank you very much for your help,

Sorry I couldn't offer a direct solution.
