Software Requirements
- R, get from [CRAN]
- Bioconductor, get from [Bioconductor]
- Bioconductor packages. Install as needed:
- Biobase
- GEOquery
source("http://www.bioconductor.org/biocLite.R") biocLite("PACKAGE")
Obtaining GEO Datasets
- Open a R terminal
- Load Biobase and GEOquery packages
libary(Biobase) library(GEOquery)
- Can load:
- datasets - GDS
- measurements - GSM
- platforms - GPL
- series - GSE)
gds <- getGEO("GDS162") #load GDS162 dataset
