Hello friends

I am doing micro array data analysis(HGU1333plus2), i got the expression matrix file by using gcrma , but the some probe is represent multiple gene like this . how can we treat this, then some probe is not matched it shows NA can delete it , next i take this file for analyze WGCNA , please share your knowledge ,

Dear Mathavanbioinfo,

i think you have asked the same question in a recent previous post that it has been already answered:

How to combine multiple probes representing a single gene?

Also, some suggestions about preprocessing with WGCNA can be found here:
