Hi Gautam, Sorry I was not able to get to this yesterday (we were just finishing the Unidata User's Workshop, and I was helping an attendee to understand the GEMPAK download, installation, and configuration processes. > I am trying to convert an AREA file to a netcdf file using IMGCOPY > and am getting the following output > > IMGCOPY BLIZZARD/G7-VIS-4K.1 NETCDF/ALBEDO.1 > Beginning Image Data transfer, bytes= 308128 > Transferring AREA data outbound, bytes= 308208 > imgcopy.k: MCAOUT rc= -1 > imgcopy.k: done > > I am also including the output of dsserve cmd. > > >DSSERVE > Group/Descriptor Type Format & Range RT Comment > ------------------------ ----- ------------------ -- > -------------------- > GOES10/IR2 IMAGE AREA 3201-3400 GOES-West Band 2 > - SWIR > GOES10/IR3 IMAGE AREA 3401-3600 GOES-West Band 3 > - IR > GOES10/IR4 IMAGE AREA 3601-3800 GOES-West Band 4 > - IR > GOES10/IR5 IMAGE AREA 3801-4000 GOES-West Band 5 > - IR > GOES10/VIS IMAGE AREA 3001-3200 GOES-West Band 1 > - Visible > GOES12/IR2 IMAGE AREA 2201-2400 GOES-East Band 2 > - SWIR > GOES12/IR3 IMAGE AREA 2401-2600 GOES-East Band 3 > - IR > GOES12/IR4 IMAGE AREA 2601-2800 GOES-East Band 4 > - IR > GOES12/IR6 IMAGE AREA 2801-3000 GOES-East Band 6 > - IR > GOES12/VIS IMAGE AREA 2001-2200 GOES-East Band 1 > - Visible > NETCDF/ALBEDO IMAGE NCDF 6061-6080 > NETCDF/TEMPERATURE IMAGE NCDF 6081-7000 > TEMP/ALBEDO IMAGE AREA 6001-6020 > TEMP/TEMPERATURE IMAGE AREA 6021-6060 OK. The output dataset, NETCDF/ALBEDO looks to have been created using the following DSSERVE command: DSSERVE ADD NETCDF/ALBEDO NCDF 6061 6080 TYPE=IMAGE One quick recommendation that has nothing to do with the problem you are reporting: it is always a good idea to include a textual explanation for datasets you create. For instance, your DSSERVE command could have looked like: DSSERVE ADD NETCDF/ALBEDO NCDF 6061 6080 TYPE=IMAGE "netCDF FOMAT IMAGE FILES and the DSSERVE LIST output for this dataset would be more descriptive: NETCDF/ALBEDO IMAGE NCDF 6061-6080 netCDF FOMAT IMAGE FILES > Any help in this regard is greatly appreciated. I just created a netCDF-formatted ADDE dataset using the DSSERVE command above, and I encountered no problem creating the output image: DATALOC ADD BLIZZARD ADDE.UCAR.EDU Group Name Server IP Address -------------------- ---------------------------------------- BLIZZARD ADDE.UCAR.EDU <LOCAL-DATA> indicates that data will be accessed from the local data directory. DATALOC -- done DSSERVE ADD NETCDF/ALBEDO NCDF 6061 6080 TYPE=IMAGE "netCDF FOMAT IMAGE FILES Adding the group NETCDF as a local dataset Group/Descriptor Type Format & Range RT Comment ------------------------ ----- ------------------ -- -------------------- NETCDF/ALBEDO IMAGE NCDF 6061-6080 netCDF FOMAT IMAGE FILES DSSERVE: done IMGCOPY BLIZZARD/G7-VIS-4K.1 NETCDF/ALBEDO.1 Beginning Image Data transfer, bytes= 308048 Transferring AREA data outbound, bytes= 308128 IMGCOPY: BLIZZARD/G7-VIS-4K.1 copied to NETCDF/ALBEDO.1 IMGCOPY: done The name of the netCDF image file that should get created is ALBEDO0001.nc, and this will be written to your $MCDATA directory by default (~/workdata for the user 'mcidas' and ~/mcidas/data for all other users if you configured accounts as per recommendations in the Unidata McIDAS web pages). Questions: - what is the value for $MCDATA ? - I _assume_ that you have write permission in the directory; true ? McIDAS has a file facility, REDIRECT, that has top priority in determining where a data (and ancillary data) files will be found/read/written. If you have a file REDIRECTion in place for files named *.nc, it could be that you do not have write permission for the that directory. Please check to see if you have a file REDIRECTion in place: <as the user that is having the problem being reported> REDIRECT LIST -- and/or -- DMAP *.nc and then let me know what you find. It is possible that the problem you have reported is related to you running under MacOS-X, but we will not know this until things like file write permissions are investigated.
