[BioC] methylumi

[Noemi Andor]

Hello everybody,

I'm currently working with Methylation data. Three data types:
IlluminaDNAMethylation_OMA003_CPI_CPI,
IlluminaDNAMethylation_OMA002_CPI_CPI

both from Illumina Golden Gate BeadArray platform 

and

Illumina Infinium Human DNA Methylation 27 platform 

After several trials, I finally succeeded loading the data into R(after reorganizing it into one single file - like in the example-data from the methylumi-package in R)

But how do I get the mappings of the probe, e.g. 

Composite Element   Cy3	                 Cy5	Detection Pvalue
cg08367223	9.75030715328155	51.3125	  3.68E-38

Interpretation:   Cy5/Cy3 > 0 --> location x is hypermethylated,

But where is this location x? Are there some mappings, similar to cdf-files from Affy-data, or is the location somehow encoded in the Composite element.

The OMA003-platform for instance has comosites such as:

SOX17_P303_F

this means, it refers somehow to the SOX17 - gene, P303 - position 303 starting from startcodon? F?

would be very greatfull for some tipps.

thank's,

Noemi
