分子动力学中构象的可视化

Visualizing Conformations in Molecular Dynamics

Christoph Best, Hans-Christian Hege

摘要:

复杂分子动力学的蒙特卡罗模拟产生具有大量不同构型的轨道以采样构型空间。预期这些构型可以被分类为代表分子形状的本质变化的少量构象。我们提出了一种方法来可视化这些构象的点集在平面上的基础上的几何距离测量个别配置之间。事实证明,不同的构象表现为分离良好的点集。通过对数据集进行聚类分析,进一步改进了该方法。点簇表示用于控制三维分子查看器应用程序,以显示单个构型和构象变化。讨论了基本坐标的提取和分子形状的可视化。

英文摘要:

The Monte Carlo simulation of the dynamics of complex molecules produces trajectories with a large number of different configurations to sample configuration space. It is expected that these configurations can be classified into a small number of conformations representing essential changes in the shape of the molecule. We present a method to visualize these conformations by point sets in the plane based on a geometrical distance measure between individual configurations. It turns out that different conformations appear as well-separated point sets. The method is further improved by performing a cluster analysis of the data set. The point-cluster representation is used to control a three-dimensional molecule viewer application to show individual configurations and conformational changes. The extraction of essential coordinates and visualization of molecular shape is discussed.
