microarray , R package oligo and summarised level
I am using R package oligo for microoarry analysis. In oligo user guide I found that oligo can summarise an exon array in 3 possible options; i.e. core, full, and extended. I like to know
- what basis these 3 summarisation work?
- what is possible logic I need to select one of them? or it is just my wish?

Another answer: It's about how one 'summarises' the expression across one or more probes / probe-sets. In most cases, you will want 'core'. I have given answers on this:
- Human Exon array probeset to gene-level expression
- How to map probeset associated statistics to gene statistics in microarray differential expression analysis?
The choice is up to you about which to use.
