The Lifespan Machine v2

Nicholas Stroustrup Centre for Genomic Regulation http://lifespanmachine.crg.eu

This repository contains v2 of the lifespan machine software, comprised of

  1. Scanner control software ( ns_image_server ) for the distributed high-throughput microscope system first described in Stroustrup et al. "The C. elegans Lifespan Machine". Nature Methods 2013
  2. Image analysis software ( ns_image_server ) that extracts survival data from lifespan machine data sets
  3. Visualization software ( ns_worm_browser ) for inspecting and annotating images and automated analysis.

For additional documentation, please take a look at:

  • The software installation guide: doc/lifespan_machine_software_installation.pdf
  • The software tutorial: doc/lifespan_machine_software_tutorial.pdf
  • The 2013 methods paper: doc/nmeth.2475.pd
  • The 2013 methods paper supplement: nmeth.2475-S1.pdf
  • The 2021 methods update paper: https://doi.org/10.1101/2021.03.31.437415
