摘要：
Free energy calculations are indispensable for characterizing the conformational transitions of proteins. The dominant transition path can be regarded as a minimal free energy path (MFEP) on a free energy landscape (FEL). However, it takes computational costs to find an MFEP. In this study, we propose a post-process to estimate an approximated MFEP. In our method, an initial string consisting of beads is generated and relaxed using local centroids on the pre-prepared FEL to estimate the MFEP. The implementation in Python is available as a jupyter notebook from the website https://github.com/riquri/post-string.
