Your control file has time templated. The time index defaults to 1 when you first open the control file. So check if the file 1981/mld.19810101_0000 exists. I guessed the name of this file based off of the DSET entry in the control file (which tells Grads where to look for the data files) and the TDEF entry. Since the path I just mentioned seems relative, make sure you run Grads from the directory that contains these files. Otherwise the control file will not find the data and you'll get that error. So check on that first.<div>
