This looks OK.

Hmm...  Are the IMGCOPY and IMGDISP outputs from the same McIDAS session?

This is a bit weird.

OK, with this ADDE server mapping table setup, the images
created from your IMGCOPY should be stored in the files:

LOC/POS.952  -> AREA0952
LOC/POS.954  -> AREA0954
LOC/POS.956  -> AREA0956

The first thing to check is if the images actually got created:


> [~/mcidas/data] $ redirect.k LIST ALL
> AREA1* /data/voldata
> AREA5* /data/voldata
> AREA6* /data/voldata
> AREA7* /data/voldata
> AREA8* /data/voldata

Yes, but what about AREA0*?  If there is no file REDIRECTion for AREA0*
then the output images should be created in your McIDAS working directory.
This would be ~/mcidas/data for the non-'mcidas' user and ~/workdata for
'mcidas' _if_ you setup your account(s) according to the instructions
in the Unidata McIDAS-X Users Guide.

This comment makes me suspicious about if the output images were actually

> Could you tell me what caused this problem?

Please send the output of the DMAP command I included above.

No worries.
