As with other types of microarray platforms, technical artifacts are a concern, including background fluorescence, dye-bias from the use of two color channels, bias caused by type I/II probe design, and batch effects. Several approaches and pipelines have been developed, either targeting a single issue or designed to address multiple biases through a combination of methods. We evaluate the effect of combining separate approaches to improve signal processing.

I found a new-ish method, RUVm, for removing unwanted variance between batches using negative controls. This works well after NOOB.
Should I plan to port this from R into methylprep?

Let’s hold off for now on RUVm for now. We may need to optimize our pre-processing pipeline, and need a strategy for empirically evaluating the utility of each step.
