I don't know if/where the overview lives. It may not have made it onto 
the website as yet - perhaps Herve knows?

This sessionInfo is different than what you should get if you run the 
commands below. For instance, oligo isn't loaded. Additionally, you 
don't really want to load both oligo and affy, as they share some 
function names so you will end up with masking of things you will need, 
such as rma(). In other words, if you load oligo and then affylmGUI, the 
rma() that you will get comes from affy rather than oligo.

So you are going to be unable to use affylmGUI to analyze these data, as 
this package assumes you are planning to use affy to do the 
normalization/summarization, and as you know this is done with oligo for 
these chips. So at this time your only recourse is to use the 
command-line tools in the oligo package.

The segfault is irrelevant to this analysis, but hopefully Keith 
Satterley will see this thread (or you could contact him directly) in 
case you want to use affylmGUI for other analyses.
