WEBSERVERS / CODE / SOFTWARE
The GenePlexus repository contains data and code to generate/reproduce the results in our work on systematically benchmarking supervised-learning for network-based gene classification across diverse prediction tasks (functions, diseases, and traits) and molecular networks using meaningful validation schemes and evaluation metrics. We have designed the code to enable easy addition of new methods, which can then be benchmarked along with the other methods using the same evaluation environment.

The ASD webserver contains a genome-wide ranking of human candidate genes associated with Autism Spectrum Disorder (ASD), predicted based on known ASD-related genes and their functional relationships in a human brain-specific gene interaction network (from GIANT; below). Using the ASD webserver, researchers can interactively access all autism gene predictions in the context of their relationships in the human brain-specific gene network, along with the results from subsequent analyses, including spatiotemporal brain signatures, functional modules and prioritized copy-number variants (CNVs).

The GIANT webserver contains data-driven human genome-scale functional interaction networks between ~26,000 genes in more than 280 tissues and cell-types. Using GIANT, researchers can (i) look-up the tissue-specific interactions of one or more genes, (ii) compare a gene's functional interaction in different tissues by selecting the relevant tissues in the dropdown menu, and (iii) reprioritize functional associations from a genome-wide association study (GWAS) using tissue-specific networks using an approach named NetWAS and identify additional candidate disease-associated genes.
