Summary: Biological systems comprise a vast amount of intricate processes that are deeply intertwined and carefully coordinated in order to enable complex functions. Internal and external challenges can introduce major disruptions to such systems requiring dynamic functional adaptions on how the corresponding processes interact. However, complex disruption patterns are hard to capture and analyze, particularly when focusing on biomarkers individually without accounting for their dependencies. To address this, we provide CoDi , an easy to use and highly flexible open-source package that allows to quantify disruption characteristics of biomarker networks across conditions and timepoints, and discover modules with exceptional disruption profiles. CoDi employs the notion of correlation disruption which quantifies functional disruptions and enables a novel perspective on the coordination and adaption of biological systems to internal and external challenges. Our examples illustrate the scope of CoDi , by revealing coordinated functional adaptions of the immune system during pregnancy.
