Hi Bioconductors,

following the lumi vignette I was hoping to analyse some IlluminaHuman
v3 data, but I'm curious about the resulting annotation - especially
with regards to the nuIDs.

briefly:

> library(lumi)
> fileName<-'raw_data.txt'
> x.lumi<-lumiR(fileName, lib='lumiHumanV2')
> lumi.N.Q <- lumiExpresso(x.lumi)

If I look at the resulting data:

$iUYoe44olUvV11drzA

but... what are these 000 prefixed numbers?

$`0006370768`
