[BioC] appyPLM residual plots: any hint?

[Stefano Calza]

Hi.

I'm using affyPLM models to check for some array quality. Here you can see the plots of the residuals

www.med.unibs.it/dip/dip_SBB/sez_statist/calza/bioinfo

So, afaik some of those chip look a bit suspicious to, i.e. LptMOE8 and LptMOE9 and also LptMOE11 and LptMOE12. How should I interpret those 
"stains"? Are this array that bad? Is it reasonable to exclude those probes from the analyses (and is it possible)?

TIA,
Stefano
