[BioC] affy mouse promoter tiling array analysis

[Joern Toedling]

Hello,
there are a number of packages that could help you with the
normalization. For example, have a look whether the function
"normalizeByReference" from package "tilingArray" is useful for you.
Once you have an ExpressionSet of normalized data, the packages Ringo
and ACME may be useful for identification of ChIP-enriched regions.
Best regards,
Joern

By using makePlatformDesign and oligo packages, I have successfully read in the *.cel files. Now, I am stuck for the next step. Which package should I use for normalization and further statistic analysis? This is my first time dealing with CHIP-chip tiling array. Would anyone kindly help me out?
