It's got to be there somewhere, not sure where your IDE is hiding it.

Instead of $out.stat, you might try an explicit path.  For example, if  
you're on a Mac, you might try

stat.file = /Users/jimin/Desktop/out.stat

(or something like that)

Or if you're on Windows you might try something like:

stat.file = c:\documents and settings\jimin\desktop\out.stat

(or maybe...)

stat.file = c:/documents and settings/jimin/desktop/out.stat

(I'm not sure how Java interacts with paths in Windows)

Also your file doesn't have to be named out.stat, so you could try:

stat.file = $my.file

And then search for "my.file" on your hard drive.

Thanks, I'll check the tutorial.  The parameter has now changed to:

pop.subpop.0.species.ind.tree.0.print-style=c

There are two options you can try also:

pop.subpop.0.species.ind.tree.0.c-operators=false
pop.subpop.0.species.ind.tree.0.c-variables=false

The tutorial should work just fine still; though it's true the current  
version has made a bunch of improvements.
