Dear AutoDock Vina user: Thank you for your inquiry. AutoDock software is downloaded at the rate of many thousands a year. As you can imagine, it is not feasible for me to provide email support to all those interested in it, except a select group of collaborators. Support is best sought in the user forums, accessible from http://vina.scripps.edu/forum.html . I personally attempt to answer Vina-related questions in the forum, approximately once a week. However, other participants may provide timelier help. Strictly following the forum posting guidelines may increase the likelihood of getting assistance as well as its quality. Best of luck, -- Oleg Trott, Ph.D. (Columbia University) http://olegtrott.com
