Dear Bioconductor Community,

I am currently working with HTA 2.0 microarray data and using the oligo package for RMA normalization. I have encountered a few questions and would appreciate any guidance.The platform I use is GPL17586.

(1) After performing RMA normalization with oligo::rma(), I noticed that the extracted matrix contains multiple types of probe IDs. I would like to conduct differential expression analysis using gene symbols. Is it appropriate to directly convert the probe IDs to gene symbols, or is there a risk of introducing errors in the process?
