Karli,

re: UWGRID in 7.60

Yes, the sequence would be:

o install 7.60
o enable GRID decoding:

  <as 'mcidas'>
  cd ~mcidas/workdata
  decinfo.k SET DMGRID ACTIVE

o add the running of the Bourne shell script uwgrid.sh to cron.  You
  will have to edit uwgrid.sh (installed in ~mcidas/workdata) and
  set MCDATA, MCPATH, etc. to match your system setup.  The times
  you kick off uwgrid.sh (this simply runs the McIDAS command uwgrid.k)
  will depend on when you typically get NGM and MRF data, so you will
  have to do some investigation to figure this out.

OK.

Hmm...  Did you check the directory permissions on ~mcidas/workdata/LWPATH.NAM?
They should be set so that 'mcidas' owns it and everyone in the same
group as 'mcidas' has read/write permissions.

No, that really should have worked.  Remember that each user that wants
to access those images will have to have the same REDIRECTion for
his/her McIDAS-X sessions.

The current LDM release is at 5.0.8.  Are you referring to ldm-mcidas
perhaps?

Yes.

>Should there be any mayor concerns I must be aware of?

First I want to be sure that you are talking about the LDM and not
ldm-mcidas.

There are binary distributions for both the LDM and ldm-mcidas
(decoders for Unidata-Wisconsin datastream) packages, so you don't have
to build anything if you grab and install those.

I am curious, are you running on IRIX or IRIX64 (I suspect IRIX64)?
