EMMAX is a statistical test for large scale human or model organism association mapping accounting for the sample structure. In addition to the computational efficiency obtained by EMMA algorithm, EMMAX takes advantage of the fact that each loci explains only a small fraction of complex traits, which allows us to avoid repetitive variance component estimation procedure, resulting in a significant amount of increase in computational time of association mapping using mixed model.
The current implementation of EMMAX is under beta status and is available for download. Note that the current version provides only 64-bit linux binaries compatible with GLIBC 2.4. The official release should be available any time soon. If you have you any further question, please feel free to contact Hyun Min Kang. Until the official release, the latest source code is available only upon request.
