[BioC] Probe-level analysis of exon arrays using xps

[Lavorgna Giovanni]

As you guys know, there is a growing evidence showing that a probe-level analysis  (as opposed to a probeset-level or a gene-level analysis) could be useful in analyzing Exon arrays. I am currently analyzing several human exon chips (185!) on a 4 GB machine and I am using the xps package. I would like to stick to this software since it allows to manage several chips with the resources at hand and I was wondering if anyone has ever tried to perform probe level analysis using xps. Also, I would be grateful if anyone could point out alternative resources to perform this job.
Thanks in advance.
Giovanni
