叠加3d
注:有这个库的C ++版本。
用法
def Superpose3D ( X , # <-- Nx3 array of coords for the "frozen" point cloud
x , # <-- Nx3 array of coords for the "mobile" point cloud
# ---- optional arguments: ----
w = None , # optional weights for the calculation of RMSD
allow_rescale = False , # attempt to rescale mobile point cloud?
report_quaternion = False ) # report rotation angle and axis?
Superpose3D()接收两个xyz坐标
计算核酸backbone的RMSD的TCL脚本
一般在VMD中使用
The protein backbone is defined as C, N, and O atoms composed of the amide bonds, and the RNA backbone is defined as C, O, and P atoms composed of sugar-phosphate moieties.
