Recent advances in brain imaging and high throughput genotyping and sequencing techniques enable new approaches to study the influence of genetic variation on brain structure and function. HDBIG is a collection of software tools for high dimensional brain imaging genomics. These tools are designed to perform comprehensive joint analysis of heterogeneous imaging genomics data. HDBIG-IGEA is an HDBIG toolkit focusing on high dimensional brain imaging genetics enrichment analysis. The current version includes R implementation of two-dimensional imaging genetic enrichment analysis for identifying high-level imaging genetic associations using enrichment strategy. See below for a list of relevant papers.
