Hi, I am kan!

Recently I found some datasets from GEO, but they are produced by illumina platform, and I don't know which kind of data should I download for further analysis? And the normal workflow for analysis?

 

Download:

1. Download family-Series Matrix File(s)

or

2.Supplementary file-RAW.tar or _non-normalized_data.txt.gz

or 

other data

Thanks!!

Hi Kan, You can use lumi package to do the analysis from the raw data (https://bit.ly/2C1lg2E).

See Sections 4.6 and 17.3 of the limma User's Guide:

http://bioconductor.org/packages/release/bioc/vignettes/limma/inst/doc/usersguide.pdf

To read and normalize the Illumina Beadchip data you can use:

> library(limma)
> x <- read.ilmn("GSE57691_non-normalized_data.txt.gz",probeid="ID_REF",expr="Sample ")
Reading file GSE57691_non-normalized_data.txt.gz ... ...
> y <- neqc(x)
Note: inferring mean and variance of negative control probe intensities from the detection p-values.
> group <- rep(c("smallAAA","largeAAA","AOD","Donor"),c(20,29,9,10))

Then you're ready to go with a limma analysis.
