OK, great.

Under the McIDAS portion of the Unidata website under Documentation are
links for:
User's Guide
Learning Guide
Training Workshop
You could slog through this material and figure things out, but I think it
will be quickest if I give a brief overview of how data is accessed in
McIDAS first.
1. access to the forms of data supported by McIDAS is provided through
the Abstract Data Distribution Enviornment (ADDE)
ADDE is a server interface for the types of data supported:
IMAGE, POINT, GRID and TEXT
2. one must create ADDE datasets from the data that s/he wants to
be able to view/analyze
An ADDE dataset is exactly like it sounds: sets of data, or
said another way, sets of data of like kinds
3. McIDAS provides a utility, DSSERVE, that creates a persistent
table that defines the sets of data/datasets that McIDAS can
visualize/analyze
The absolutely best thing about ADDE is that it can provide
access locally or via remote TCP access.
Setting up remote access requires some actions to be performed
by 'root', but local access is done in the local account.
So, what is meant by creating a dataset?
One uses the DSSERVE utility to tell McIDAS where to find sets of
like files, what type of data is in the files, potentially how many
elements there can be in the dataset, and provide a human readable
description for the data.
Let's take a concrete example...
You said that you want to use McIDAS to verify the integrity of
some image files you get/have gotten from the UW/SSEC Data Center.
The first question to be answered is what is the naming convention
that was used for the files?
Examples:
Historically named image files of the form AREAnnnn, where nnnn is
a 4-digit number that can range from 0001 to 9999 (NB: nnnn is
always a 4-digit number!)
AREA0001
...
AREA1234
...
AREA9999
Images that are in the McIDAS AREA file format, but named differently:
10.7_20181009_1845
etc.
Let's assume that you got a number of images from the SSEC Data Center
that are all from the same satellite. Let's further assume that the
images are all in files that follow the AREAnnnn naming convention.
The easiest thing to do is to create a directory somewhere on a disk
that your McIDAS session can access (meaning read). Let's call this
directory:
/home/mcidas/workdata/Meteosat-8
Put all of the Meteosat-8 images you got from SSEC in this directory,
and make sure that they are readable by 'mcidas'.
The simplest form of an ADDE dataset for this set of images can
be created from within a running McIDAS-X interactive session as
follows:
DSSERVE ADD MET8/IMAGES AREA TYPE=IMAGE
DIRFILE=/home/mcidas/workdata/Meteosat-8/AREA* "Meteosat-8 images from UW/SSEC
DSSERVE - the utility
ADD - the action which says add a definition to a table (RESOLV.SRV)
MET8/IMAGES - the ADDE dataset name which is composed of a group name of MET8
and a descriptor of IMAGES
AREA - the format of the image is AREA
TYPE=IMAGE - the files are images; NB: this is redundant if the format is AREA
DIRFILE= - a regular expression that describes the set of images you want
included
in the dataset MET8/IMAGES
"Meteo... - a human readable comment
After doing this, you should then be able to run:
IMGLIST MET8/IMAGES.ALL
and get a listing of all of the images you put in the
/home/mcidas/workdata/Meteosat-8
directory.
Please let me know that you have been successful in the above.
Next, it is more convenient to further organize the sets of images
(this applies to other data types, but let's focus on imagery for now).
Let's assume that you have images for different wavelength channels;
perhaps AREA0001 - AREA0009 are VISible images. You can create an
ADDE dataset definition for those VIS images as follows:
DSSERVE ADD MET8/VIS AREA TYPE=IMAGE
DIRFILE=/home/mcidas/workdata/Meteosat-8/AREA000\. "Meteosat-8 VIS images from
UW/SSEC
Since McIDAS understands the traditional AREAnnnn naming convention, this
same dataset definition can be made in a slightly different way:
DSSERVE ADD MET8/VIS AREA 1 9 "Meteosat-8 VIS images from UW/SSEC
This tells McIDAS that the set of files is the namespace:
AREA0001
AREA0002
...
AREA0009
Notice that I did not include the TYPE=IMAGE keyword since McIDAS understands
that files of type AREA are images.
Please try some of these dataset definitions and then let me know if you
are then able to do things like:
IMGLIST MET8/IMAGES.ALL FORM=ALL
IMGDISP MET8/IMAGES.1; MAP
etc.
