Nested Effects Models

An R/Bioconductor package to reconstruct phenotypic hierarchies from high-dimensional phenotying screens.

nem - Nested Effects Models to Reconstruct Phenotypic Hierarchies

The package 'nem' allows to reconstruct features of pathways from the nested structure of perturbation effects. It takes as input
(1.) a set of pathway components, which were perturbed, and
(2.) high-dimensional phenotypic readout of these perturbations (e.g. gene expression or morphological profiles).
The output is a directed graph representing the phenotypic hierarchy.
