The AI4Science group develops software for the simulation of molecular processes.

Our principles for scientific software development are

  • clean design and reusable code
  • ensuring correct functionality by unit and integration tests
  • extensive documentation and sample notebooks
  • automatic testing and deployment of each release on all target platforms
  • open-source policy and development via Github
  • workshops to provide hands-on training to users  

We believe that the benefits of this effort outweigh the time and costs involved to maintain it: Software development and dissemination will increase the impact of developed methods,  help to maintain group knowledge, serve the community and ensure reproducibility of results.

PyEMMA is a Python library for the estimation, validation, and analysis of kinetic models from MD data. Functionalities include dimension reduction techniques such as the time-lagged independent component analysis, clustering, maximum-likelihood and Bayesian estimation of Markov State Models and Hidden Markov Models, coarse-graining and analysis of kinetic models, computation of transition pathways, and visualization tools.

ReaDDy: High-performance simulator for reaction-diffusion dynamics with interacting particles. Suitable for modeling cellular signal transduction, chemical microreactors, soft matter systems, membrane mechanics, virus assembly etc. Previous version was Java-based. New version currently developed with software abstraction layers: (i) Python user API, (ii) C++ API, (iii) Multithreading/CUDA/MPI kernels for execution of different platforms.
