Robb,

THanks for the tips.  We were actually trying to get two diffent

files with different model times out of gribtonc and I'm wondering if this may be problematic.

Theresa,

This is not a problem, but you must have 2 pqact entries going to
different files.

We were trying to use this in the pqact.conf files HDS ^(H[HRT][I-P]A..) KWB. ([0-3][0-9])([0-2][0-9]).*(/mAVN|/mSSIAVN)

     PIPE      /usr/bin/gribtonc
     -q "lin,dlat=1.25,dlon=1.25"    /usr/etc/avn-1.25x1.25.cdl

/pub/suomiday/level1a/ancMet/ancMet_(\2:yyyy).(\2:ddd).\3.00.0360_nc

HDS ^(H[HRT][I-P]C..) KWB. ([0-3][0-9])([0-2][0-9]).*(/mAVN|/mSSIAVN)
    PIPE      /usr/bin/gribtonc
    -q "lin,dlat=1.25,dlon=1.25"    /usr/etc/avn-1.25x1.25.cdl
    /pub/suomirt/level1a/ancMet/ancMet_(\2:yyyy).(\2:ddd).\3.00.0360_nc


We did continue getting normal looking files with the 1st call, but
the 2nd call resulted in problems.  We could use an alternate CPU
for the 2nd file we want if having 2 pipes into gribtonc with 2

separate output files is not doable.

I just noticed that both output files from the pqact entries  have
the same name. I believe that's the problem because one cannot have 2
pipes going to one file and get consistent results. One doesn't have to do
any special things, just 2 pqact entries going to different output
files should work fine.

Robb...

Thanks,
Tersa
