Hi all,

I want to form a list for the sites covered on an Illumina methylation 450k array. Theoretically, I know this information should be in the manifest file (.bpm), but I am having difficulty extracting it.

In R, I have have tried using the illuminaio readBPM function, but I'm not able to interpret the output and it does not seem to contain the chromosome and position.

Do you have any suggestions about where I can find this information? I'm looking to make a table of "Chromosome_BasePair" and just need to know where this information is stored and how to access it.

Thanks in advance!
