20030110: McIDAS IMGREMAP failure from Perl script

Glad to hear the problem is solved.

>So here is the old problem that we tried to send you in December:
>I am having trouble where none had previously existed. We have a series of
>commands one includes a remap.k
>here is the output of the debug
>/home/mcidas/bin/imgremap.k* Write to server has failed. Wanted  5120
>/home/mcidas/bin/imgremap.k*                                Did  -1

This sounds like either an ADDE dataset setup problem, or the
output dataset references AREA files that are not writable, or are
in a directory that the user running the script does not have
write permission for.

>We are also experiencing problems with simple cp commands in the

>Any clues?

A failure of 'cp' really does make it seem like a permission problem for
output directories/files.

Is it writable by the user 'ldm'?

Is the alias 'SAT' known in the environment you are trying to run the
script in?  If not, this may be your problem.

???  Was something dropped from this sentence.

>If I run that command by hand as McIDAS it works fine...I cannot run it as
>LDM because it gives an error stating that it cannot open source

Can't open source directory?  This is not ringing any bells.

>i figure it would not work because the environements are not set.
>Here is the kickoff environment:

This looks correct.  Does 'ldm' have write permission in the $MCHOME/workdata


Looks OK

># export the environment variables so that they can be used
>As I said...it used to work...I do not know what has changed!

When something starts failing after working, I always suspect permission

>It appears to be some sort of permissions problem but we cannot isolate
>it! Please help.

Can I get a login to the environment(s) where you are trying to run the
script?  This would likely speed up the sleuthing process.  Without
seeing all aspects of the problem, I would be simply guessing possibilities.
