It's my first-time to analysis Affymetrix HTA 2.0 arrays [transcript (gene) version], data source https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi. As a rookie, I have been bothered by its annotation for a long time, really hoping there would be someone teach me something. Thank you in advance!
The data probes like this: At first sight, there are 5 kinds of probes in this data？Sorry for my weak knowledge of probe sets.
Referring to some experience in Bioconductor, I used hta20transcriptcluster.db package to complete annotation, however, there are so many NA in the last result. I must have missed something. Are there someone so kind to help me understand my faults?
Thank you very much.
