请问下老师 跑回旋半径的colvars的话,要怎么设置啊?我参照手册里但是没看到除了atoms外的关键词,我之前是这么设置的,但是感觉跑出来的轨迹的rg值对不上。
colvar { # Define a new variable
name rg1 # Must give a name to this variable
# width 0.2 # Estimated fluctuation amplitude and/or grid resolution, "w_d"
gyration { # This variable is a distance between centers of mass (COMs)
atoms { atomNumbers 521 822 844 916 950 1055 1079 2225 2530 2552 2611 2645 2753 2777 3812 4117 4139 4211 4245 4350 4374 5555 5872 5894 5966 6000 6105 6129 } # List the atoms of the 1st group
}
}
harmonic { # Define a harmonic potential, 1/2*K*(d-d0)^2/w_d^2
colvars rg1 # Apply it to the variable "d"
centers 1.7 # The center of the potential, "d0"
forceConstant 956.0 # Force constant, "K"
