付老师,您好,在使用eabf进行多维度的pmf计算时,虽然能够继续计算,但是总会出现以下提示的错误:
colvars: Integrated in 144 steps, error: 9.96932e-07 colvars: Integrated in 128 steps, error: 9.25099e-07 colvars: Integrated in 1 steps, error: 7.02279e-07 colvars: Integrated in 1 steps, error: 6.7063e-07 colvars: Synchronizing (emptying the buffer of) trajectory file "emeta_d-nc_573.colvars.traj". colvars: Saving collective variables state to "rest.colvars.state". colvars: Integrated in 1 steps, error: 5.93777e-07 colvars: Integrated in 1 steps, error: 5.7674e-07
用的是Lammps计算的, 版本号为:Initializing the collective variables module, version "2019-08-05". Using LAMMPS interface, version "2019-08-01".
