From: SNP by SNP by environment interaction network of alcoholism
The SNP×SNP×E network of Alcoholism. The network contains 397 SNPs and 15 demographic variables. The nodes represent variables and an edge between two nodes represents their dependency quantified by conditional probabilities. For the node labels and the complete list of interactions see Additional file 3: Table S2. To enhance the quality of representation, we have removed the “alcoholism” node and the edges from this node to all other nodes
