Hi everyone,

I have a microarray dataset which platform is 'Illumina HumanWG-6 v3.0 expression beadchip'. I want to know the corresponding gene symbols of each probeset. Where can I find the gene annotation files of this platform? I couldn't find it in there website.

Thank you very much for your help.

Best,

Li

It depends on what format you are looking for. I would assume you want something that will work well within an analysis setting that includes Bioconductor packages, in which case you want to do

source("http://www.bioconductor.org/biocLite.R")
## or if you have already done this previously,
library(BiocInstaller)
biocLite("illuminaHumanv3.db")

Which will install the correct annotation package for this array (note that the HumanHT-12 array has the same content as the HumanWG-6 array, just for more samples).

But if you want Illumina's version of the correct file, it's here: http://support.illumina.com/content/dam/illumina-support/documents/downloads/productfiles/humanwg-6/humanwg-6_v3_0_r3_11282955_a.zip

Does that help?
