Re: [gmx-users] set computer time on REMD simulation

2017-12-17 Thread Qinghua Liao
Hello, If I understand correctly, it terminates at 0.99*t, t is the time you set in hour. In you case, you simulation should be terminated at 0.1*0.99 = 0.099 h, which is 5.94 minutes. PS: 0.1 h is not 10 minutes, but 6 minutes. All the best, Qinghua On 12/18/2017 08:05 AM, YanhuaOuyang wro
