HapCluster++ is a software package for linkage disequilibrium mapping using coalescent theory. It is based on a Bayesian Markov-chain Monte Carlo (MCMC) method for fine-scale linkage-disequilibrium gene mapping using high-density marker maps. HapCluster++ is a C++ implementation of the method described in the paper "Fine Mapping of Disease Genes via Haplotype Clustering" by E.R.B. Waldron, J.C. Whitaker, and D.J. Balding. Genetic Epidemiology. 30: 170–179. (2006).
Diagnotep is an affliction search engine to help diagnose medical problems. It searches among the symptoms of a medical database, so the results will only be medical afflictions. The links from the results page point to affliction pages which are either public domain government pages or pages licensed under the GNU Free Documentation License.
The National Library of Medicine Insight Segmentation and Registration Toolkit (ITK) is a software system to support the Visible Human Project. Segmentation is the process of identifying and classifying data found in a digitally sampled representation. Registration is the task of aligning or developing correspondences between data. For example, in the medical environment, a CT scan may be aligned with an MRI scan in order to combine the information contained in both.
