Now builds with cmake; conversion to python3
AmberTools consists of several independently developed packages that work well by themselves, and with Amber20 itself. The suite can also be used to carry out complete molecular dynamics simulations, with either explicit water or generalized Born solvent models.
The AmberTools suite is free of charge, and its components are mostly released under the GNU General Public License (GPL)
