Dilek, Does your variable have non-positive values? If so, taking the log will give you NA or nan for those entries. If you have a variable X1, then something like "D1 = (X1>0)" will generate a dummy variable equal to 1 for positive values of X1. You can do this from the console, or from the GUI. Click Add, define new variable, then enter the corresponding formula in the dialog box. I hope this helps.
