Need help in extract and save expression data from Agilent
Dear all,
I have a set of data from "Agilent-012391 Whole Human Genome Oligo Microarray G4112A". I used Agilp package to extract and save gene expression data.
The below is the code I used as provided by the author.
library(agilp)
inputdir<-file.path(system.file(package="agilp"),"extdata","", fsep = .Platform$file.sep)
outputdir<-file.path(system.file(package="agilp"),"output/", "", fsep = .Platform$file.sep)
AAProcess(input = inputdir, output = outputdir, s = 9)
This is the error: "Error in [.data.frame(data, , "ProbeName") : undefined columns selected".
Any comments are greatly appreciated.

robina user interface software can analyze agilent data
Are you looking at the feature extracted text file? Also, is it public data?
If it's public, please share the file link; if not, can you paste first few lines (including headers) of your file here?
