Microarray analysis workshop

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)
  5. Linear models for Microarray analysis (limma) (15 mins - Marcus Davy)
  6. Experimental analysis ("45mins")

+Bioconductor/R framework

+R tasklist

    • tasks available from web which utilze example data available in R - object assignment, subsetting, plotting, mathematical functions, sorting etc (20 tasks?)
  • Usage/interaction within environment
  • Bioconductor resources/vignettes(including downloading)
  • Bioconductor basics (any resources for limma out there?)
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
Analysis script (1+hours)
