Hi Luis,

No worries.

Is that because the dataset containing the images they want to look
at is not supported in the MCGUI?  If yes, the MCGUI can be configured
to support other datasets.

McIDAS has a command that will save a raster version of a displayed
image.  The command, FRMSAVE, can save in a variety of formats:

HELP FRMSAVE
FRMSAVE -- Saves a McIDAS frame to a GIF, PPM, BMP, JPEG or PostScript file
   FRMSAVE frame name <keywords>
   FRMSAVE window name TYPE=COMBINE <keywords>
Parameters:
   frame | image frame number to save (def=current)
   window | combined window number (created with COMBINE command); the
            range is 0-9; you must also specify TYPE=COMBINE with this
            option
   name | name of the file in which to save the frame; if you don't
          specify an extension, .GIF is appended if FORM=GIF, .PPM is
          appended if FORM=PPM, .BMP is appended if FORM=BMP, .JPG is
          appended if FORM=JPG, .PS is appended if FORM=PS, and .CPS
          is appended if FORM=CPS
Keywords:
 ...

Unfortunately, PNG is not one of the formats that FRMSAVE supports.

>All the images are in the ~mcidas/workdata and ~ldm/data
>directories??

Images can be anywhere you want, and they can reside on machines that
are accessible over TCP/IP Ethernet.  As far as where the recommended
location for images ingested by the LDM from the UNIWISC IDD stream, it
is ~ldm/data/mcidas, or ~ldm/data/gempak/...

If folks there were looking at images from one of the 'GINI' datasets
(GINICOMP, GINIEAST, or GINIWEST), or from the GOESEAST dataset, they
were looking at holdings on servers in different parts of the country.

Cheers,

Tom
