Mohammed,

You are receiving only the 0Z & 12Z runs because you are requesting output
on the #211 grid in your pattern (^Y.Q...) ['Q' indicates the #211 grid].
The 211 grid output only appears on the 0Z and 12Z runs, whereas the #212
grid (mesoETA) appears on 06Z and 18Z as well.  (I'm not sure about the
output on the #215 grid since I don't get that one.)  To get the 212 grid
you will need to modify your pattern to something along these lines (this
is from the distributed gempak pqact):

# NOAAport ETA grids
# Grid #211 80km CONUS:    ^[YZ].Q.*/mETA
# Grid #212 40km CONUS:    ^[YZ].R.*/mETA
# Grid #215 20km CONUS:    ^[YZ].U.*/mETA
# Grid #214 47.5km Alaska: ^[YZ].T.*/mETA
# Select any/all grids desired from [QRUT]
#HRS    ^[YZ].[QRUT].*/mETA
#       PIPE    decoders/dcgrib2 -d data/gempak/logs/dcgrib.log
#               -e GEMTBL=/home/gempak/NAWIPS/gempak/tables
#

So you will need a separate pattern action line in pqact.conf for the
212 something like this:

HRS     ^[YZ].R... .* ([0-3][0-9])([0-2][0-9]).*/mETA      FILE
/data/wx/hrs/\1:yy)(\1:mm)\1\2eta212.gbm

Also be aware that the 212 output is *much* larger than the 211 output.
My gempak 211 files are around 10MB, but the 0Z & 12Z mesoETA are around
94MB, and the 6Z & 18Z files are 73MB, so you can extrapolate to what the
sizes of the grib output might be.
