近年来,反应分子动力学 (Reactive MD simulation) 模拟方法被广泛用于研究许多复杂分子系统的反应机制,如燃烧、爆炸和非均相催化。针对大体系的长时间MD模拟会产生非常复杂的轨迹文件,其中包含着大量的反应和分子(物种)。人工分析如此复杂的轨迹是不现实的。为解决这一难题,我们开发了ReacNetGenerator软件。它以轨迹中的原子坐标为唯一必要的输入,可根据原子之间的连接关系自动判断物种和反应。然后将统计后的反应种类、数量和反应网络展示在一个交互式的网页上。用户通过鼠标点击即可对指定物种参与的局部反应网络进行分析。值得一提的是,ReacNetGenerator采用了隐马尔科夫模型来有效过滤轨迹中的噪声,突出主要反应。该软件同时支持并行计算,并在内存使用方面进行了大量优化,因此运行效率很高,可用来分析大型轨迹文件。
ReacNetGenerator主要使用Python语言开发,其中部分模块也利用了C++、HTML、JavaScript和CSS等语言,以及一些第三方软件库。得益于Python语言的跨平台特性,以及pip和conda的打包功能,ReacNetGenerator可在Linux、macOS和Windows等多个操作系统安装和使用。
conda install reacnetgenerator -c conda-forge
reacnetgenerator -h
