[BioC] SNPRMA: Normalizing...Error in readChar(con, 5) : cannot open the connection

[Alex Lisovich]

Dear All,

I am getting the following error when using snprma() on oligo
v.1.0.2-6 with pd.mapping250k.sty which I believe was once discussed
on the list on June 4, 2007 (see below):

>library(oligo)
>library(pd.mapping250k.sty)
>rawData<-read.celfiles(list.celfiles())
>rma<-snprma(rawData)

I am wondering if this problem was solved and if yes what was a solution.

Thank you in advance for your help!

Alex
