The decoders seem to be running and MDXX >files are being created, but it doesn't appear that the data is being >written correctly. When trying to plot data using McGUI, little to no >data is ever displayed. Did you create ADDE datasets from the data that is being produced? In a nutshell, the pieces of getting McIDAS to access data created by XCD are (I list the steps just to make sure that you didn't leave out any step): - register as a Unidata user - download the distribution into the 'mcidas' account - set the McINST_ROOT enviornment variable (typically /home/mcidas if this is the HOME directory of the user 'mcidas') - unpack the distribution - CD to the McIDAS source directory cd mcidas2004/src - build the distribution: make all <- builds McIDAS-X and McIDAS-XCD - install the distribution: make install.all - setup file REDIRECTions that tell McIDAS where to read/write data files: <as 'mcidas'> cd ~mcidas/data cp EXAMPLE.NAM LOCAL.NAM <edit LOCAL.NAM and set the directories to match your setup> cd ~mcidas/workdata redirect.k REST LOCAL.NAM - copy files from the McIDAS distribution to the directory in which you want to run XCD and ldm-mcidas decoders. Example assuming that the output data directory is /data/ldm/mcidas: <as 'mcidas'> cd ~mcidas/workdata te.k XCDDATA \"/data/ldm/mcidas cp ~mcidas/data/SCHEMA /data/ldm/mcidas cp ~mcidas/data/SYSKEY.TAB /data/ldm/mcidas cp ~mcidas/workdata/ROUTE.SYS /data/ldm/mcidas cd /data/ldm/mcidas chmod 664 SCHEMA SYSKEY.TAB ROUTE.SYS mkdir bufr grib - copy the XCD run script (xcd_run) to a directory in the PATH of the user running the LDM (typically ~ldm/util or ~ldm/decoders) - edit the XCD run script and set variables to match your setup (may require no modification) - configure the LDM ~ldm/etc/ldmd.conf file to run the XCD run script: exec "xcd_run MONITOR" - configure the LDM ~ldm/etc/pqact.conf file to run the XCD decoders through the XCD run script: IDS|DDPLUS .* PIPE xcd_run DDS HDS .* PIPE xcd_run HDS - setup data scouring for McIDAS-XCD produced data files: run the mcscour.sh script from cron for the user running the LDM; copy mcscour.sh from ~mcidas/workdata to a directory in the PATH of the user running the LDM. - run the XCD setup BATCH scripts as 'mcidas' <as 'mcidas'> cd ~mcidas/workdata batch.k XCD.BAT batch.k XCDDEC.BAT - optionally enable decoding of GRIB data into McIDAS GRID format (warning: this takes a lot of disk space): decinfo.k SET DMGRID ACTIVE - stop and restart the LDM You should be at this point. You are not, however, finished yet: - create ADDE datasets for the data that will be decoded by XCD and ldm-mcidas decoders: <as 'mcidas'> cd ~mcidas/data cp DSSERVE.BAT LSSERVE.BAT cp DATALOC.BAT LOCDATA.BAT edit LSSERVE.BAT and change anything you need to change; NOTE that you may need to make modifications in LSSERVE.BAT to match where you setup ldm-mcidas decoders to create output files! Also, if you are ingesting and saving NEXRAD Level III radar data, you should change the lines in LSSERVE.BAT that reference a NEXRAD.CFG file: change NNEXRAD.CFG to MSUNEXR.CFG cd ~mcidas/workdata cp NNEXRAD.CFG MSUNEXR.CFG <edit MSUNEXR.CFG to set DIRMASK and FILEMASK to regular expressions that match the directory(ies) and file names for your NEXRAD Level III data files) batch.k LSSERVE.BAT <- *** this creates McIDAS ADDE datasets - setup the remote ADDE server (for access by non-'mcidas' users, this is the easiest way to configure for multiple users) >I built the software on a Sun-Blade 1000 running Solaris 9 (SPARC). The >LDM is running also running on a Sun-Blade 1000 with Solaris 9 (SPARC) >- the McIDAS software is accessed via NFS (The ADDE server and LDM are >on two separate machines, but the McIDAS data directory is on the same >machine as the LDM). Since the data is being decoded, it is most likely that the only thing left to be done is the creation of ADDE datasets. See above. >I am not real sure where to begin... > >1) XCD Processes Are Running: > >% ps -ef | grep inge | grep -v grep >ldm 12917 12889 5 13:39:33 ? 0:38 ingetext.k DDS >ldm 12889 12878 0 13:39:31 ? 0:00 ingetext.k DDS >ldm 12888 12878 0 13:39:31 ? 0:00 ingebin.k HRS >ldm 12916 12888 1 13:39:33 ? 0:03 ingebin.k HRS > >% ps -ef | grep start | grep -v grep >ldm 12879 12876 0 13:39:31 ? 0:00 startxcd.k >ldm 12918 12879 0 13:39:33 ? 0:00 startxcd.k Looks good. >2) Sample Contents of Data Folder (/data/mcidas): > >% date >Thu Jan 20 13:59:30 EST 2005 > >% ls -lm MD* >-rw-rw-r-- 1 ldm wx 49999236 Jan 20 13:39 MDXX0009 >-rw-rw-r-- 1 ldm wx 338536 Jan 20 06:30 MDXX0010 >-rw-rw-r-- 1 ldm wx 44560 Jan 19 18:49 MDXX0019 >-rw-rw-r-- 1 ldm wx 151312 Jan 20 02:53 MDXX0020 >-rw-rw-r-- 1 ldm wx 16640 Jan 19 18:49 MDXX0029 >-rw-rw-r-- 1 ldm wx 112752 Jan 20 13:38 MDXX0030 >-rw-rw-r-- 1 ldm wx 8007456 Jan 20 13:59 MDXX0059 >-rw-rw-r-- 1 ldm wx 887448 Jan 20 06:51 MDXX0060 >-rw-rw-r-- 1 ldm wx 5951016 Jan 20 01:45 MDXX0069 >-rw-rw-r-- 1 ldm wx 17360 Jan 20 13:37 MDXX0070 Looks OK, but some of the data files look awfully small. >% ls -lm *XCD >-rw-rw-r-- 1 ldm wx 17418960 Jan 19 18:59 DD050190.XCD >-rw-rw-r-- 1 ldm wx 2147483647 Jan 20 13:59 DD050200.XCD > >% ls -lm ZZ*IDX >-rw-rw-r-- 1 ldm wx 811008 Jan 19 18:59 ZZ05019.IDX >-rw-rw-r-- 1 ldm wx 396951552 Jan 20 13:59 ZZ05020.IDX > >% ls -lm SCHEMA >-rw-rw-r-- 1 ldm wx 465408 Jan 19 18:10 SCHEMA > >% ls -lm SYSKEY.TAB >-rw-rw-r-- 1 ldm wx 24000 Jan 20 02:53 SYSKEY.TAB > >There are a number of *IDX files and time stamps on many of those files >indicate that data is being captured.

So, it looks like you _do_ have ADDE datasets setup. Since you can list the datasets using PTLIST, you should be able to view their contents through the MCGUI. >4) XCD Status: > >When running "statdisp", the "DDS" and "HRS" data source entries are >listed in white letters and continually update.

Can I get on your system as 'mcidas' to take a quick look? >By the way, speaking of remote ADDE servers - There seems to be a list >of sites available in the "Configure | ADDE Dataset Location" menu of >the McGUI application.

No. These are servers that owners have allowed general access to for the Unidata community. >I have a faculty member that would like to access >data from the RTPTSRC group next week and if I am unable to get things >to work locally, I may need to have her point to a remote ADDE server. It really does sound like you setup everything correctly. I guess that the quickest thing would be for me to login and look around to see what I can see. If you setup the ADDE remote server for your machine, I could try out access to the data from here; this may point out some problems, and, then again, it might not. >Thanks. No worries.
