Input data For computing epicenters: a tab delimited file with 3 columns (source, target and weight of edge), “disease_network”, “compute_cshan?” and “percentile_threshold”. For extracting immediate influence zone and highlighting dysregulated genes: network from which to extract influence zone, nodes around which to extract influence zone, node weights, fold change, control-specific highest activity network, disease-specific highest activity network, upstream limit, downstream limit and fold change limit.
Output data For extracting immediate influence zone and highlighting dysregulated genes: immediate influence zone (edges) around each epicenter, node information of immediate influence zone for each epicenter, the table similar to table 1 in the paper and summary statistics of each influence zone.

Unbiased Identification of Blood based Biomarkers for Pulmonary Tuberculosis by Modeling and Mining Molecular Interaction Networks

PMCID: 5233809
PMID: 28065665
DOI: 10.1016/j.ebiom.2016.12.009

[…] a change at that node can transmit across the network, leading to the identification of the most influential nodes, also known as epicenters. the ripple centrality measure was computed using the epitracer algorithm (), which measures the outward reachability of a given node, a property of its connections as well as its condition-specific node weight. of the 276 upregulated nodes, 153 nodes […]
