Each McIDAS user can create his/her own server table.

The error you report implies that your MCPATH includes the
/home/disk/data/mcidas directory, and that a user other than yourself
created a RESOLV.SRV in that directory, AND you do not have write
permission for it.

What is the setting of MCPATH in your Unix login?

The recommendation is that the first directory in each non-'mcidas'
user's MCPATH be ~/mcidas/data.  This directory should be owned by you,
so it should be writable.

If you do have ~/mcidas/data as your first MCPATH directory, and if
it is writable by you, and McIDAS is still trying to write to
an existing copy of RESOLV.SRV in /home/disk/data/mcidas, then
do the following to force McIDAS to look for RESOLV.SRV in a
directory you have write permission to:

REDIRECT ADD RESOLV.SRV "/home/ovens/mcidas/data

(assuming that your HOME directory is /home/ovens; if it is not, adjust
the path you are specifying).  After setting this REDIRECTion, McIDAS
should look for (i.e., read and write) RESOLV.SRV in your ~/mcidas/data
directory, and so the DSSERVE command should work.

No.  DSSERVE is simply writing a file that is then read when a
local dataset needs to be defined/resolved.

Cheers,

Tom

re: REDIRECT ADD RESOLV.SRV "/home/ovens/mcidas/data

That REDIRECT fixed it!  And now I can display the GINI images,
hurray!  Thank you.
