Sounds good. >The McIDAS passes its tests. Good. >The LDM seems to be receiving McIDAS files from typhoon.atmos.ucla.edu >according to ldmadmin watch. OK. The McIDAS files are the ones in the Unidata-Wisconsin datastream. The data to be decoded by McIDAS-XCD come in the DDPLUS|IDS and HRS datastreams. You will have to remember to request these be fed to your machine in addition to the MCIDAS feed. >When I ran ldmadmin start it hung At this point, I would kill all of the LDM processes (try running 'ldmadmin stop', but kill ones by hand if necessary) and make sure that ~ldm/ldmd.pid gets deleted.

Did you: o stop the LDM <login as 'mcidas'> o verify that 'mcidas's MCDATA, MCPATH, and MCGUI environment variables are set correctly o copy SCHEMA to the XCD output directory and link this copy to the MCIDAS output directory (you wouldn't have to do this if those directories were the same). This appears to be /home/data/xcd on your system: cd data cp SCHEMA /home/data/xcd cd /home/data/xcd ln SCHEMA /home/data/mcidas o setup REDIRECTions cd data cp EXAMPLE.NAM LOCAL.NAM <edit LOCAL.NAM and setup directories to match your installation For this, I recommend that you combine /home/data/mcidas and /home/data/xcd, but this is not a big deal> o cd ~/workdata o start a McIDAS-X session and: REDIRECT REST LOCAL.NAM TE XCDDATA "/home/data/xcd BATCH XCD.BAT BATCH XCDDEC.BAT Make sure that you now have several .RAP files in /home/data/xcd. If you don't, it probably means that /home/data/xcd was not writable by the user 'mcidas'. If it wasn't, rerun the XCDDEC.BAT BATCH file as listed above. As soon as: o the LDM is requesting the DDPLUS|IDS and HRS data o and XCDDEC.BAT has been successfully run as 'mcidas' (proving that the REDIRECTions in LOCAL.NAM are correct) you should start seeing LOTS of files being created by XCD decoders. >For one thing I am not sure what I should be putting in pqact.conf >and ldmd.conf. > >In ldmd.conf I have the line > >request MCIDAS ".*" typhoon.atmos.ucla.edu If this is the only request line, then all you will be getting is AREA files. From the inclusion below, these will be going into the /home/data/mcidas directory. You probably want this machine to get all of the data, so you need to modify your request line to be: request UNIDATA|FSL2 ".*" typhoon.atmos.ucla.edu >Because I only want to receive the McIDAS AREA and Gridded data >on this machine. Is that correct? If you only want to receive MCIDAS files, then your original request line is correct. The Unidata-Wisconsin feed no longer has GRID files in it, so this will not get you any gridded data. To get gridded data, you will need to request the HRS feed (a part of the UNIDATA pattern above) and decode the HRS products into McIDAS GRID files using XCD. >In pqact.conf I have: >------------------------------------------------ ># Entries for XCD decoders > >DDPLUS|IDS ^.* PIPE > xcd_run DDS >HRS ^.* PIPE > xcd_run HRS ># >#### Unidata-Wisconsin channel image (AREA) files ># >MCIDAS ^(LWTOA3 .*) > PIPE -close > lwtoa3 -d /home/data/mcidas -v -l /usr/local/ldm/logs/mcidas.log -xv >------------------------------------------------ The entry for XCD decoders is correct, but it won't do anything until you get DDPLUS, IDS, and HRS data. You have to request to be fed this data in ldmd.conf. >I put in DDPLUS|IDS and HRS because the guide said to and the MCIDAS >LWTOA3 because that one is working on our obsolete system.

That data was removed from the Unidata-Wisconsin datastream on July 1 of this year. The only way to get conventional (e.g. MDXX) and gridded (e.g. GRID) data is by running XCD. >If you can't find anything obvious in what I have described, can >I arrainge for a phone conference in the near furture or perhaps >I could give you a password to ATM12 to inspect what I have done. The access to the machine will be helpful. I will be back in the office tomorrow afternoon and will try to help you out. Tom
