Hi there,

I have been running two-color microarray data from Agilent and I would like an advice to convert GeneBank Access number into Entrez gene IDs?

Cheers

How you do that depends on the species you are working with. Let's assume you have human data.

> library(org.Hs.eg.db)
> select(org.Hs.eg.db, "U43746", "ENTREZID","ACCNUM")
'select()' returned 1:1 mapping between keys and columns
  ACCNUM ENTREZID
1 U43746      675

There are many orgDb packages that you can install, and even more that you can get on the AnnotationHub. I would recommend reading the vignettes for the AnnotationDbi and AnnotationHub packages to get yourself acquainted.

Thanks for your tip, James. I will check it.

I have just tried it. I was not able to do that.

I would like to convert SystematicName(GeneBank Access Number) into Entrez gene IDs. Could anyone help me?
