2015 Biology of the Genomes conference at Cold Spring Harbor, NY has been going since tuesday 5th May. Overall, we have been hearing about really impressive genomics. On the poster session today, I came across an interesting new bias correction method for ChIP-seq data. Georg Stricker from Julien Gagneur lab in Gene Center of the University of Munich (LMU) presented a poster in BOG15.
The new method is based on Generalized Additive Models (GAMs).
Quoting the poster authors:
it smoothly models the coverage tracks as piecewise polynomials and is able to extract the signal component from the data.
Several thumbs up points for this framework:
Also really cool is that using smoothed coverage tracks allows for a simple way to find peaks based on the function and its derivatives.
Worth watching out for this one when it is out!
