*Network Coherence Calculator* is an app designed to calculate the network coherence of a set of differentially expressed genes within a biological network. As of version 2.0, the app is also able to accept a file containing expression data for multiple samples as an alternative to a list of genes. The app then offers a rudimentary functionality of computing sample-level gene sets with high expression levels and returns a network coherence for each such set. Network Coherence Calculator is able to use any network loaded into Cytoscape as the biological reference network, provided the nodes and gene sets follow a common naming scheme.
