# SeSAMe-Minfi interaction

SeSAMe can be converted back and forth from Minfi RGChannelSet in multiple ways. One can sesamize a minfi `RGChannelSet` which returns a `GenomicRatioSet`. Here we are illustrating using the `FlowSorted.Blood.450k` object, which is distributed in the `minfi::RGChannelSet`.

    library(sesame)
    library(FlowSorted.Blood.450k)

    grSet <- sesamize(FlowSorted.Blood.450k[,1:4])
