Giovanni,

No problem!

OK.  So you are assuming that all files in all directories matching
/export/home/met171/giova/area/*/* are images in AREA file format.
Is this what you intended?

Yes, but how are you separating these images from each other?  With the
dataset definition listed above, you would have to specify a dataset
position number to get a particular image.  It seems to me that a
better way to create datasets is to organize your images by type
(VIS, IR, WV, etc.) and make separate datasets with each type.

Something like:

DSSERVE ADD MYIMG/VIS AREA DIRFILE=/export/home/met171/giova/area/VIS/VIS_*
DSSERVE ADD MYIMG/IR  AREA DIRFILE=/export/home/met171/giova/area/IR/IR_*
DSSERVE ADD MYIMG/WV  AREA DIRFILE=/export/home/met171/giova/area/WV/WV_*
etc.

>I can display 1km VIS images with this kind of names: VIS_010710_1555
>but MAP says " Unable to find a NAV start point in image"

This is very strange.  What does an IMGLIST for the VIS_* images look
like?

Do you mean that you can't display images in these files?  If not, I
would guess that they are not in AREA format, or they might have been
damaged in the FTP process you used to get them from the NPS.

>All happens regardless the options and keywords I'm using, eg
>IMGDISP MYIMG/AREA.32, for defaults

Again, the files in question may not be in AREA format.

Would it be possible for me to either FTP the files you have so I can
take a look, or login as you and see what I can see in your environment?

re: try
   SF 1
   ERASE
   MAP NA
>this works I can see the North America Map, but what I said unfortunately
>doesn't change! sigh! :(

OK.

re: also try
   DATALOC ADD GINIWEST PAPAGAYO.UNL.EDU
   DSINFO I GINIWEST
   IMGDISP GINIWEST/GW4KIR STA=KLAX MAG=-3 REFRESH='EG;MAP H'
  
>this works fine!! ;)

This further reinforces the notion that the image files that you are
unable to look at are either not in AREA format or are somehow damaged.

>let me know if need something more or to come in and take a look at our
>system. the images are still under my homepage

The quickest thing for me to do is login as you so I can run McIDAS in
your environment.  This way I could quickly determine if the files
you are trying to look at are good or bad.
