Dear list,

I am now analysis hgu133plus2 array. I want a CDF which has been
removed probes with SNPs. Because I want to remove the the noise
caused by single nucleotide polymorphisms (SNPs) in different samples.
Also I do not want some probeset which sequences can mapped to
multiple genome position.

In bioconductor, there is a package hgu133plus2cdf. I also noticed
there is a website provide custom CDF file for hgu133plus2.

The website is:
HGU133Plus2 (Version 15.0.0, ENTREZG)

Is the same for this two CDF files?

Or the package hgu133plus2cdf directly from Affy CDF file?

Thank you very much in advance.
