Dear ALL,
i have recently acquired some affymetrix CEL files, with genechip Human Transcriptome Array 2.0 in order to identify possible alternative splicing events. As I'm fresh in R and Bioconductor, any tutorials or papers i have found focused on human exon ST 1.0. Thus, i would like to ask if anyone has used the above genechip in R and how much the workflows from human exon ST are different and from some proposed pipelines:

So far, i tried to import the CEL files with oligo :
but it doesnt make any sence in summarizing in the probeset level or transcript level
Any suggestions or ideas ?
The SCAN algorithm supports this (http://www.bioconductor.org/packages/release/bioc/html/SCAN.UPC.html). I'd be interested to know your impression on how the results look when you do the summarization at the probeset/transcript levels.
Thank you Stephen for the above package--i would definately check it, but my main issue as i see from other threads or literature is that there isnt a tutorial or pipeline for HTA-2.0 for exon analysis, such as Human Exon ST-1.0(of course there are quite different genechips). Nevertheless, my other solution would be the open-source application AltAnalyze, for which i found quite interesting(although it is more of an application)
also your link above doesnt work
The original link included a trailing ')', which I have fixed.
