Hi!
SAD is quitting with messages like below; any idea what might be the problem? I could not resolve the problem by searching on-line. I notice the RESID file is left busy...
ZMSGOP: FILE DA01:MSD000000.000; NOT FOUND
ZTTOP2: error translating /dev/pts/0
ERROR 2 ASSIGNING OUTPUT TO /dev/pts/0
ZMSGOP: ZTTOPN RETURNS ERROR = 1 FOR LUN = 6
ZMSGOP: FILE DA01:MSD000000.000; NOT FOUND
...
AIPS 1: TASK QUIT WITHOUT RESUMING ME
My procedure invoking IMEAN and AIPS repeatedly on 1024 channels gets through channel 791 fine, then fails on channel 792. This channel is in a group of channels with considerable RFI... can that be the reason? If so, I can flag those channels.
What does “WITHOUT RESUMING ME” mean?
Thanks for any thoughts you have on this! A more complete log is below.
Best wishes,
Bob Gray
