Uses of Tiling Arrays
Target Application
mRNA gene expression changes
transcript validation/discovery
DNA sequencing; genotyping
DNA CGH: copy number changes
ChIP-enriched DNA Protein binding sites
transcription factor binding sites
DNA methylation sites
histone modification sites

Some tools for tiling array:
CisGenome
An integrated tool for tiling array, ChIP-seq, genome and cis-regulatory element analysis

Tutorial of CisGenome
https://biogibbs.stanford.edu/~jihk/CisGenome/index_files/tutorial.htm
Files of two types are required, bpmap file and cel file(affymetrix). They are used for intensity normalization.
Then the data are intergrated with genome annotation to retrieve the DNA sequences.
