fCCAC: functional canonical correlation analysis to evaluate covariance between nucleic acid sequencing datasets

SummaryComputational evaluation of variability across DNA or RNA sequencing datasets is a crucial step in genomic science, as it allows both to evaluate the reproducibility across biological or technical replicates, and to compare different datasets to identify their potential correlations. Here I present fCCAC, an application of functional canonical correlation analysis to assess covariance of nucleic acid sequencing datasets such as chromatin immunoprecipitation followed by deep sequencing (ChIP-seq). I exemplify how this method can reveal shared covariance between histone modifications and DNA binding proteins, such as the relationship between the H3K4me3 chromatin mark and its epigenetic writers and readers.\n\nAvailabilityR code is publicly available at http://github.com/pmb59/fCCAC/.\n\nContactpm12@sanger.ac.uk
