Calculation of Free Energy

How do I calculate Free energy by using " ti " command.
I have read the manual but I am not getting that.

Please help me out.
If you can send an example with an in file or a fraction of
in file only mentioning the commands, then it would be better.

Thank you.

There is no simple answer to that question.

You can ask Sai (CCd) about how he uses
the ti command for his systems since he
added it to LAMMPS.
