Dear BioConductor experts, I wonder if anyone would be generous enough to share some scripts/screen images they use to analyze Affy ST gene arrays, either for human or mouse. I am particularly interested in learning what packages they use and what the output files look like. Thanks much, Yongde Dept. Microbiology University of Virginia

Hi Yongde, I am no expert but for the last Human Gene 1.0 ST array data I analyzed I used the xps package for pre-processing and then to assess differential expression I used the limma package. I am sorry I don't have any screenshots but both packages have nice documentation in their vignettes, which should be really straight forward to follow. cheers, Achilleas On Thu, Nov 11, 2010 at 3:46 PM, YBao <yb8d@virginia.edu> wrote: > Dear BioConductor experts, > > > I wonder if anyone would be generous enough to share some > scripts/screen images they use to analyze Affy ST gene arrays, either > for human or mouse.

Thanks so much, Achilleas, for the quick response. I will try to use those two packages and see how far I can go with them.

Hi Yongde, also take a look at the oligo package for normalizing your Gene ST arrays cheers, Mark On 12/11/2010, at 8:51 AM, YBao wrote: > Thanks so much, Achilleas, for the quick response.

http://www.bioconductor.org/help/workflows/oligo-arrays/ gives a reasonably thorough discussion of relevant resources On Thu, Nov 11, 2010 at 7:02 PM, Mark Cowley <m.cowley at="" garvan.org.au=""> wrote: > Hi Yongde, > also take a look at the oligo package for normalizing your Gene ST arrays > cheers, > Mark > On 12/11/2010, at 8:51 AM, YBao wrote: > >> Thanks so much, Achilleas, for the quick response.
