Time schedule: 8:30 - 10:30am, 11-12:30am (3.5 hours)


Workflow

  1. Introduction to Microarray analysis (10mins - Marcus Davy)
  2. Normalization (10mins - Robert Schaffer)
  3. Bioconductor/R framework (15 mins - Marcus Davy)
  4. R tutorial (45mins)

Brief about Limma (10-15 mins)
  • Essentially t-statistics for each spot/gene
  • Uses between gene information in moderated t-statistics
  • Computationally fast/robust
  • Handles missing information/use defined flag information
  • benefits/limitations?
  • FDR control? → ranking better than selecting cutoff
