Mesoscale modelling with Fluctuating Finite Element Analysis (FFEA)

科学界一致认为，由于冷冻电子显微镜和断层扫描等3D细胞成像工具的发展，“结构生物学正在从主要的分子视角向更广泛的长度尺度过渡”。波动有限元分析（FFEA）是一种新型的中尺度生物分子模拟工具，由我们在利兹的研究团队开发，专门用于基于cryo-EM和cryo-ET结构数据的生物分子建模。通过这笔旅行资助，我将与关键的计算（Amaro）、实验（Chiu和Fire）和理论（Benham）团队建立合作关系，通过对细胞质动力蛋白和染色体外DNA （eccDNA）进行初步计算，扩大FFEA可解决的生物学问题的范围。目的是通过确保可用性和与其他代码的兼容性，建立一个FFEA用户的国际社区。

There is a community consensus that "Structural biology is transitioning from a largely molecular perspective to a much wider range of length scales", as a result of developments in 3D cellular imaging tools such as cryo-Electron Microscopy and Tomography. Fluctuating Finite Element Analysis (FFEA) is a novel mesoscale biomolecular simulation tool developed by our research team at Leeds which is specifically designed for biomolecular modelling based on structural data from cryo-EM and cryo-ET. Through this travel grant I will build collaborations with key computational (Amaro), experimental (Chiu and Fire) and theoretical (Benham) groups to broaden the range of biological questions addressable with FFEA by performing preliminary calculations on cytoplasmic dynein and extrachromosomal DNA (eccDNA). The aim is to build an international community of FFEA users by ensuring usability and compatibility with other codes.
