template in gribmap

[Maat, Herbert ter]

Dear GrADS-users,
 
This message was submitted to this list already a month ago, but I
haven't received any answer yet.
 
I have the following question about the utility gribmap. I have created
a set of big grib-files containing records with forecasted values at +12
and +36 of rainfall. Per year one grib-file is generated with values at
12Z, so that I have rainfall values at 0Z +1) and (0Z +2). To display
this data in GrADS I have gone through the following steps:
 
grib2ctl.pl -verf FC_PREC_%y4 > prec+36.ctl ! using the template option
c:\program files\GrADS19\win32\gribmap -e -v -f36 -i prec+36.ctl 
 
If I want to display the data at t=367 (e.g. time=00ZJAN021961), which
is actually 12ZDEC311960 + 36) I get the following error message. I
guess that GrADS tries to extract this data from the wrong GRIB file.
How do I overcome this problem? Any suggestions?
 
ga-> set t 367
Time values set: 1961:1:2:0 1961:1:2:0
ga-> d lsfpsfc
