本文将简要介绍如何使用四元数方法计算两个分子之间RMSD,同时附上简单的示例Python代码。 1. 什么是RMSD RMSD(Root Mean Square Deviation)是指均方根偏差,在化学中一般用于衡量一个分子结构相对于参照分子的原子偏离位置。RMSD的值越小,说明当前分子结构越接近参照的分子结构。RMSD的数学定义为[1]: RMSD(v,w)= ...

This two step (raw data to 2D features to 3D objects) approach is able to process 30 frames per second on Kinect depth data, which allows for real-time tracking and feature based robot mapping based on 3D range data.doi:10.1007/978-3-662-43859-6_2Georgiev, Kristiyan...
计算两个小分子之间的RMSD,可以用来判断两个构象的接近程度。 第一步:安装Anaconda Win或者Linux系统下Anaconda安装,不赘述,网上很多教程。 第二步:安装RDKit 通过conda安装RDKit conda install -c rdkit rdkit 第三步:使用方法 python isoRMSD.py mol1.pdb mol2.pdb rmsd.txt ...
The range must be specified with a '-' symbol. Then RMSD value for atoms 1-5 v.s. 2-6 is calculated. Other uncompared atoms will be translated and rotated according to the new orientation of compared atoms. A b_new.gjf file will be generated. This is just the new geometry of b....

The transformation calculation is heavily weighted by the coordinates of the static region of the two conformations, highlighting the range of flexibility in the overlaid structures. Lastly, we show how wRMSD fits can be used to evaluate predicted protein structures. Comparing a predicted fold to ...
