Abstract: Recent progress in sequencing technology has revolutionized the study of genomic and epigenomic processes. These assays generate massive, high-resolution Omics data often suitable to be represented as curves over the genome, whose analysis poses great challenges to standard statistical methods. Indeed, these data pose several problems such as large amounts of noise and correlations among neighboring measurements. Functional data analysis (FDA) can overcome these problems, reducing data dimension and filtering noise through smoothing, while taking advantage of the correlations among neighboring genomic positions and leveraging shape information within curves. We will present three main research directions in which FDA already proved to be effective: (1) studying and contrasting the genomic landscape of regions/loci of interests; (2) incorporating shape in the analysis of high-resolution signals of the epigenome; (3) analyzing quantitative complex phenotypes that can be represented as curves or surfaces.
