  • users want (chair), send them to home depot
    • Happy Birthday Ikea, here's your cake.x
  • Democratizing Innovation, Eric Von Hippel
  • need managed cloud: CyVerse Atmosphere, iPlant Collaborative, Jetstream
• Matthew Vaughn: Packaging computational biology tools for broad distribution and ease-of-reuse (need to get slides)

  • BioFabric: Comb the Hairball
• Scott Simpkins: Scalable tools for quantitative analysis from sequencing-based chemical-genetic genetic interaction screens
  • BEAN-counter for processing barcode sequencing data from multiplexed experiments. Originally designed for chemical genomics experiments performed in the Myers/Boone Labs, it is applicable to any experiment in which pools of genetically barcoded cells are grown under different conditions, with the resulting barcode DNA isolated from those cells combined into one 2nd-gen sequencing run via the use of indexed PCR primers.
    • not open source, must obtain license from http://license.umn.edu/technologies/20170001_bean-counter-quantitative-scoring-of-chemical-genetic-interactions

    • recommendations to discard low expressing genes (1/3 of measured dynamic range)
    • discard genes with lower log fold changes between conditions < log2FC 1~2

  • has list of housekeeping genes for humans
  • in discussion with another delegate, recommended a minimum of 7 replicates, randomized to reduce batch effects
