The license of GENESIS source code is changed from the GNU General Public License version 2 to the GNU Lesser General Public License version 3. The user manual for 1.5.1 is currently being prepared. The usage of 1.5.1 is almost the same as 1.4.0 except for the free-energy perturbation (FEP) method. If you use the FEP method, see Tutorial 15.1.
