I would suggest finding articles in the literature that have
successfully done what you want and then see which methods they used.
This email list is more for technical questions and troubleshooting
amber, and not so much for recommendations on solving scientific
problems. for that you're better off trusting peer-reviewed
literature, in my opinion. while you may get a quick answer here,
there's really no way to know if the person posting has even done the
kind of calculation you want, or if the results have been properly
validated .
