The gretl library writes out an x12a input file based on your specification in the arma() function. This file is named on the pattern $HOME/.gretl/x12arima/vname.spc where "vname" is the name of the dependent variable. The file vname.est is output from x12a, which libgretl tries to read after calling x12a. The fact that the missing file in your case is named ".est" (with no vname part) suggests that your dependent variable is anonymous. That won't work, the series must be named (that is, for a series with position i in the dataset, dataset->varname[i] must be non-empty, and should be a valid gretl identifier). strcpy(dataset->varname[i], "foo"); // max 31 characters Allin Cottrell
