how to remove sequence names and probe names from normalized agilent micro array data

Question

[rohit]

Hello everyone,

I'm analyzing the agilent microarray data using limma package. I have performed normalization using

y <- normalizeBetweenArrays(y,method="quantile")

now I need to get the normalized gene expression values. I have used the command

write.table(y, file="Tt.txt", sep="\t", quote=FALSE)

to get the expression values of genes. In the output text file I can see the gene names, expression values along with sequence names and probe names.

Is there any package to remove the sequence names and probe names?

Thank you in advance.

The easiest way is maybe to import that file into Excel, and erase the undesired columns
