[gradsusr] Templating over ENSEMBLE (EDEF entry)

[Stefano Materia]

I would like to concatenate several model outputs coming from different 
ensemble members. I edited a control file accordingly, and placed all my 
netcdf files in the same directory.  However, when I open the control 
file and attempt to display any variables (whether the e dimension is 
varying or not), I get the "cannot contour grid - all undefined values" 
error.  What is wrong?

DSET ^WAfrica_prec_19970501_%e1.nc
OPTIONS template
DTYPE netcdf
TITLE Precipitation from ISO
UNDEF  -9999

endvars

Thanks for your help,
Stefano
