Since McIDAS-Lite is not a package we support, we do not have any
experience in troubleshooting problems encountered with it.

I agree.

The comment from the Unidata Mail Archives is specific to using the Unix/Linux
distribution of Unidata McIDAS.  It does not apply to the Windows version of
McIDAS since we make the SSEC version of the Windows distribution available
'as is'.

Data access in McIDAS is through client-server interactions.  The concept
that new McIDAS users have trouble with is that the server can be on the same
machine and in the same account as the client.  We can go more into this
if/when you need.

For now, you will need to become familiar with the process of creating ADDE
datasets in your McIDAS session.  This will involve running several McIDAS
utilities from the McIDAS Text and Command window:

DSINFO
DATALOC
DSSERVE
IMGLIST
IMGDISP

You can get help on any/all of these commands by using the McIDAS HELP utility
in your Text and Command window.  For example:

HELP DSINFO

etc.

The command you will be using immediately is DSSERVE.  DSSERVE creates the 
mapping
between ADDE dataset names and the file(s) that comprise the dataset. 

By the way, it would likely help you to understand what I will present by 
working
your way through the online McIDAS Learning Guide:

http://www.unidata.ucar.edu/software/mcidas/2006/mclearn/toc.html

and/or the McIDAS Training Workshop:

http://www.unidata.ucar.edu/software/mcidas/2006/workshop/toc.html

The following is a brief example of running DSSERVE to create an ADDE dataset
that you can then use in the display of your data.

Suppose that the FY2C data you got from the SSEC Data Center was put
in the directory C:\Documents and Settings\Desktop and is named 
fy-2c_1_2005_230_0033.

You can use DSSERVE to create an ADDE dataset named IMAGES/FY2C-VIS as follows:

DSSERVE ADD IMAGES/FY2C-VIS AREA DIRFILE='C:\Documents and 
Settings\Desktop\fy-2c_1_*' "FY2C Visible images

After DSSERVE is successfully run, you should be able to access the image(s) in
the dataset:

DSINFO IMAGE IMAGES

IMGLIST IMAGES/FY2C-VIS.ALL

IMGDISP IMAGES/FY2C-VIS MAG=-5

and so on.

Again, reviewing the materials in the Learning Guide and Training Workshop
will be invaluable in learing how to use McIDAS.

> Thank you in advance!

No worries.  Please do not hesitate to ask for help if/when you need it.

Cheers,

Tom
