[gradsusr] using EDEF to create an ensemble in Grads

[Jeffrey Duda]

Jennifer,
Here's what my actual control file looks like (not just the output from 'q
ctlinfo'):

dset ^summer_%e_%y4-%m2-%d2_%h2:%n2.dat
options  byteswapped template
undef 1.e30
title  OUTPUT FROM WRF V3.1.1 MODEL
pdef 325 249 nps  163.030  375.118     -97.1640   23.0459518
xdef 1021 linear -150.3   0.10381060
ydef  489 linear   12.4   0.10381060
zdef   26 linear 1 1
tdef   61 linear 00Z14JUL2010      60MN
edef    7 names YSU MYJ QNSE MYNN25 MYNN3 Pleim BouLac
VARS   20
U             26  0  x-wind component (m s-1)
V             26  0  y-wind component (m s-1)
W             26  0  z-wind component (m s-1)
WW            26  0  omega (Pa s-1)
PH            26  0  perturbation geopotential (m2 s-2)
PHB           26  0  base-state geopotential (m2 s-2)
P             26  0  perturbation pressure (Pa)
PB            26  0  BASE STATE PRESSURE (Pa)
Q2             1  0  QV at 2 M (kg kg-1)
T2             1  0  TEMP at 2 M (K)
PSFC           1  0  SFC PRESSURE (Pa)
U10            1  0  U at 10 M (m s-1)
V10            1  0  V at 10 M (m s-1)
QVAPOR        26  0  Water vapor mixing ratio (kg kg-1)
HGT            1  0  Terrain Height (m)
RAINC          1  0  ACCUMULATED TOTAL CUMULUS PRECIPITATION (mm)
RAINNC         1  0  ACCUMULATED TOTAL GRID SCALE PRECIPITATION (mm)
PBLH           1  0  PBL HEIGHT (m)
tc            26  0  Temperature (C)
slp            1  0  Sea Levelp Pressure (hPa)
ENDVARS

You can see that 'options template' and the 'edef' line is in there.
