Dear All,

Recently, I am analyzing dna methylation data using the minfi package. I have seen minfi package is good for analyze dna methylation data using raw idat files. But in most of the cases from GEO database, I am getting only a series matrix or soft format family matrix without sentrix position and sentrix ID rather than raw idat files. In this case my questions are:

1. is it possible to handle a simple data matrix/data frame with csv/txt format to get the facility to use all function from minfi package?
2. if it's possible, then how?

I would be so grateful to you if kindly give me proper advise with example.

Advance thanks.
