templates and fixed forecast times for different runs

[Bill Bua]

Hi --

I'm running GrADS configured as below (from the q config command at the
grads command line):

Config: v1.9b4_ncep 32-bit big-endian readline sdf/xdf netcdf lats printim

Grid Analysis and Display System (GrADS) Version 1.9b4_ncep

Built Thu Sep 28 15:18:35 EDT 2006 for powerpc-ibm-aix5.3.0.0

This version of GrADS has been configured with the following options:

   o This is a 32-bit BIG ENDIAN machine version.
   o Command line editing (readline) ENABLED.
   o CIRES/CDC (http://www.cdc.noaa.gov) SDF/XDF interface ENABLED.
     Use sdfopen/xdfopen to read NetCDF files.
   o DTYPE netcdf is ENABLED; DTYPE hdfsds is DISABLED.
   o OPeNDAP (a.k.a. DODS) gridded data interface DISABLED.
   o OPeNDAP (a.k.a. DODS) station data interface DISABLED.
   o PCMDI (http://www-pcmdi.llnl.gov) LATS interface ENABLED.
     This version is configured to write GRIB and NetCDF files.
   o DAO (http://dao.gsfc.nasa.gov) Athena Widget GUI DISABLED.
   o NRL/DAO/PCMDI XA or ImageMagick Image Output DISABLED.
   o printim command for direct png/gif output ENABLED.
     (via the GD Library -- http://www.boutell.com/gd)

and I'm having trouble constructing a template for files named as follows:

pgbf<fhr>.<yyyy><mm><dd><cc> where fhr is the 3-digit forecast hour, yyyy is
the year, mm is the month, dd is the date, and cc is the forecast cycle (00,
06, 12, and 18).

What I want to do is be able to look at the forecast error for all runs at
forecast hour 06, 12, 18, 24, and so on up to 180.

I thought I could set up a control file with a template like so:

pgbf06.%y4%m2%d2%h2 (for six-hour forecasts)
pgbf12.%y4%m2%d2%h2 (for 12-hour forecasts)
pgbf18.%y4%m2%d2%h2 (for 18-hour forecasts) and so on.

For pgbf00.%y4%m2%d2%h2, everything works fine.  I get weird distorted
graphics for the data for f06, and I suspect I would for f12, f18, ....

Here is the control file I've tried without success:

dset /global/shared/stat/pra/pgbf06.%y4%m2%d2%h2
index ^pgbf00.2008012400.idx
undef 9.999E+20

xdef 144 linear 0.000000 2.500000
tdef 900 linear 00Z24jan2008 6hr

and so on with variable definitions.

Can anyone give me a hand with this?

Thanks!
