This has _no_ bearing on the problem you are seeing, however. >i can see the data location in Raul's IDV under adde.itc.nl, Meaning exactly what? Since you mention below that you tried to access the dataset through the remote ADDE interface using McIDAS, please check let me know the results of the following commands: DATALOC LIST MYDATA DSINFO IMAGE MYDATA IMGLIST MYDATA/IMAGES.2001 FORM=ALL TRACE=1 The TRACE=1 keyword should cause a file named 'trce' to be created in the ~mcidas/mcidas/data directory. You can then read 'trce' to find out what is wrong. >but when i try to access it i get the following: > >Inquiry: An error has occurred: >Creating image sequence >Problem with McIDAS AREA file: edu.wisc.ssec.mcidas.AreaFileException: >Error opening AreaFile: edu.wisc.ssec.mcidas.adde.AddeURLException: No >images satisfy the selection criteria This is an IDV error that I am not familiar with. I would first check to make sure that the permissions on the AREA file that you created are such that the user running the remote ADDE server code (should be 'mcadde') can read that file. Also, it may be possible that the image you created (AREA2001 ?) is in a directory that is not being searched by the remote ADDE server invocation. This would mean that the file is not in a directory in the MCPATH specified in ~/mcidas/.mcenv, or in a REDIRECTion specified in the file LWPATH.NAM that should be located in ~mcidas/workdata. Also, if, for some reason, there is a copy of LWPATH.NAM in the ~mcidas/mcidas/data directory, it could be that copy is being used for file REDIRECTions for the remote server. >This indicates that the requested image that does not exist. Or is not 'findable' (or is not readable ?). >I tried to >reproduce the same problem, but now using McIDAS-x 2004 as client >(running on the same machine serving data), and it also tells me the >dataset is empty.

I strongly suspect that the remote server invocation can not find the file you created. Where, by the way, is the file you created? >The other data pointers i can access using both IDV as McIDAS-X 2004 as >clients succesfully, telling us the ADDE server part itself is properly >functioning. OK, this is important to know. I suspect that the file you creat ed is not being found by the remote ADDE interface. As I mentioned above, I would make sure to put the file in a directory specified in the MCPATH defined in ~mcidas/.mcenv. I would also make sure that there is not a REDIRECTion in effect that is telling the remote server to look in the wrong directory for the file you created.
