Giovanni,

Too bad.

re: what does an IMGLIST look like

This looks OK.

re: possible images in non-AREA format, or damaged from FTP
>mmmmhh it doesn't seem likely, since I have 10 150 Mbyte tar files, and
>only those kind of images can not be displayed, from any tar file.

OK, I agree with your reasoning.

I downloaded all three of these images and created an ADDE dataset
that encompassed all of them just like you:

<all images were put in my /home/mcidas/images directory>

DSSERVE ADD MYIMG/AREA AREA DIRFILE=/home/mcidas/images/* "Test images from SJSU

I am able to load AND map the third image (in VIS_010713_0025) with no
problems.

Like you, I am able to run IMGLIST on the second image (in
NCAL_010713_2130), but I can not display it with IMGDISP.

I can't even successfully run IMGLIST on the first image (in
LCLD2_010708_0230).

Give this, I did a quick listing of both files and see that the
navigation blocks in each file contains a LOT of garbage.  How they are
displayable under GEMPAK I can't explain, because they are bad!

>you can also come in and run mcidas. Since we are under a firewall you

I probably don't have to do this given that the files look bad.

As I understand your messages, you have a large number of NCAL_* and
LCLD2_* images.  Is this correct?

I will play around with them more tomorrow to see if I can figure
anything out that would allow you to look at them.

>take care an thanks again!

Sorry for the bad news.
