20010913: LDM Data for GEMPAK/NWX

Patrick,
First, if you are getting data in directories like:
data/US/KDSM/00/SA43.wmo,
then it sounds like you need to comment out the sample/test
pqact.conf example in the original pqact.conf file that is
distributed with the LDM, eg:
# Bin all the (Non-GRIB) WMO format data, using elements from the
# identifier as path components. The minutes portion of the timestamp,
# and the retransmit code is ignored. The day of the month portion
# of the timestamp is not used as a path component, so it would be
# a good idea to run 'scour' on a less than 24 hour basis.
#
# "ASUS42 KRDU 012259" gets filed as
# data/US/KRDU/22/AS42.wmo
#
#WMO ^([^H][A-Z])([A-Z][A-Z])([0-9][0-9]) (....) ([0-3][0-9])([0-2][0-9])
# FILE data/\2/\4/\6/\1\3.wmo
##
That is a sample entry. Not generally usable, and almost impossible
to scour efficiently.
Next, in Gemenviron, the variable TEXT_DATA will be used by NWX to tell where
the top of the $GEMDATA/nwx tree will be. As long as you have $GEMDATA
defined wherever your ~ldm/data/gempak directory is (or linked to),
then you will be OK. The pqact.conf examples for nwx on the web page
are set to file under ~ldm/data/gempak/nwx and won't need any modification
so long as your ~ldm/data directory is pointing or linked to where you expect
your
data to be files. The FILE action in the LDM will create the directories needed
in the pqact.conf paths. You will need to create the directories used in the
PIPE
actions for decoders.
Since you say you don't see any data/gempak/nwx directories, you should make
sure
that you don't have a blank line in your pqact.conf file between where you
added the decoders.tbl and nwx.tbl. The ldmadmin pqactcheck will check the
syntax
of pqact.conf, but will stop if it hits a blank line....and pqact won't read
past that point either. So, if you are not seeing anything from any action
below the nwx section, then that could be the case. If in doubt, send me the
pqact.conf file you are using.
