RT Journal Article SR Electronic T1 CyberSco.Py: open-source software for event-based, conditional microscopy JF bioRxiv FD Cold Spring Harbor Laboratory SP 2022.03.16.484589 DO 10.1101/2022.03.16.484589 A1 Chiron, Lionel A1 LeBec, Matthias A1 Cordier, Céline A1 Pouzet, Sylvain A1 Milunov, Dimitrije A1 Banderas, Alvaro A1 Meglio, Jean-Marc Di A1 Sorre, Benoit A1 Hersen, Pascal YR 2022 UL http://biorxiv.org/content/early/2022/03/16/2022.03.16.484589.abstract AB Timelapse fluorescence microscopy imaging is routinely used in quantitative cell biology. However, microscopes could become much more powerful investigation systems if they were endowed with simple unsupervised decision-making algorithms to transform them into fully responsive and automated measurement devices. Here, we report CyberSco.Py, Python software for advanced automated timelapse experiments. We provide proof-of-principle of a user-friendly framework that increases the tunability and flexibility when setting up and running fluorescence timelapse microscopy experiments. Importantly, CyberSco.Py combines real-time image analysis with automation capability, which allows users to create conditional, event-based experiments in which the imaging acquisition parameters and the status of various devices can be changed automatically based on the image analysis. We exemplify the relevance of CyberSco.Py to cell biology using several use case experiments with budding yeast. We anticipate that CyberSco.Py could be used to address the growing need for smart microscopy systems to implement more informative quantitative cell biology experiments.Competing Interest StatementThe authors have declared no competing interest.
