[gradsusr] Opening and extracting grads file generated from fortran

Tue Jul 31 00:40:17 EDT 2012

Hi, Thank you for walking me through the process. the folder 1981 exists,
but the files were renamed to mld19810101.gpv by an external script. I
tried to change the data file to mld19810101.gpv in an attempt to open the
first file and it gives me a warning message:

ga-> open mld.ctl
Scanning description file:  mld.ctl
Warning: OPTIONS keyword "template" is used, but the
   DSET entry contains no substitution templates.
Data file mld19810101.gpv is open as file 1
LON set to 99.5 285
LAT set to -15.5 65
LEV set to 0.5 0.5
Time values set: 1981:1:1:0 1981:1:1:0
E set to 1 1

Is it possible to create .ctl file corresponding to each datafile? I also
tried to do "d mld" and gives me a message
Contouring: 50 to 450 interval 50. However, data were not displayed. Thanks
much.
