Hello All,

I am using Affy GeneChip for SFP detection and only interested in the
probe-level data. Who knows there are some PCA packages or tools that
can analyze probe-level data. I tried PCAplot in affycoretools package,
but seems it only takes expression data. Any suggestion? Thanks in
advance.

Best,
