Hi Joe,

I am suprised by this.

>I just entered 'GUI' on the
>Command Mode prompt, and then all graphics were viewed in the GUI window
>instead of the MCGUI program's window.

OK.

>I tried using 'mcidas -config' to startup McIDAS into the GUI program, and
>also to startup McIDAS into the MCGUI program.  I still wasn't able to get
>the GUI program to work.

Since I am not seeing the problem here, and since others may run into
something similar to what you have run into, I would like to pursue
getting access to the machine on which you built the code as the
user 'mcidas'.  With this kind of access, I can get to the bottom
of what isn't working and take corrective actions if/when necessary.

If you and Paul are agreeable to letting me on, please send me
the fully qualified hostname for the machine; send this information
to address@hidden  In a separate email, and without mention
of the machine or account name, please send me the password for
the user 'mcidas'.

It sure seems like a smoking gun...

OK, sounds good.

It seems to me that the code _might_ have enough information to reverse
engineer the format of data on disk.  What is your view?

Yes, I am interested.  Thanks!

Cheers,

re: reverse engineer Quorum's code

I think it would be quite hard to reverse engineer Quorum's code to see
their data format, looking at the code myself.  FSU would need permission
from Quorum to give a copy of the source code to Unidata.  There are
probably two routes to go:
1. Get instructions from Quorum on how to compile the code and then make
adjustments to the source code and recompile it.
2. 'Catch' the incoming data from the satellite receiver and convert it to
a suitable GVAR file before it is processed by the Quorum software.
Doing a cost-benefit analysis, this might not be worthwhile.  That is for
the McIDAS community, especially FSU and Unidata, to decide.

I have to put this on the back burner for now ... sorry to get folks' 
hopes up on this one, but I thought we might be able to get it to work 
on the limited time and budget frame I had to work with.  Paul
