Tools

  • MoMA a.k.a. the Mother Machine Analyzer, written by Florian Jug in collaboration with our lab: a state-of-the-art image analysis software to track bacteria growing in microfluidics channels.
  • DIMM a.k.a the Dual Input Mother Machine: a microfluidics design for long-term growth and monitoring in precisely controlled environmental conditions.
  • a collection of scripts and configuration files for quantitative light microscopy using Micro-Manager.
  • a minimalist R package to tweak ggplot2 to my taste.
  • a lightweight, responsive website template based on the Skeleton boilerplate (no javascript — except for media lightbox, no jQuery dependency, no Bootstrap dependency: loading a page transfers less than 200kb!). You’re currently looking at it ;)
