Subject: AMBER: potential of mean force: Unit of PMF energies and min path

Dear Sir/Madam,
I am a new to PMF. I run the PMF calculations, and resolved the energy with WHAM. However, I have two questions:
(1) what is the unit of energy listed in the output WHAM? Is it kcal/mol?
(2) Can we find the minimum pathway in a 2D-PMF obtained by WHAM? If yes, could you mind to teach me how? Do I need to have write a script for doing this or can I do it with the amber package?
Best regards,
