GNUmed is a comprehensive scalable software solution for electronic medical practices with an emphasis on privacy protection, secure patient centric record sharing, decision support, and ease of use. It is intended to become a sophisticated decision support system that will elevate the quality of medical care that can be delivered.
GNotary is a set of Python scripts that implement an asynchronous digital notary service. Anybody who needs certification of any digital document creates a message digest (like MD5 or RIPEMD160) of that document and submits it to the GNotary service by email. GNotary signs this email digitally (using GnuPG), retains a copy of the certified and time stamped message, and mails it back to the sender, optionally with the public key attached to allow the sender to verify the signed document. At regular intervals, the GNotary server creates message digests of its own logs and distributes them among other GNotary servers, thus making it virtually impossible to forge the chain of evidence that authenticates a submitted document.
The GNotary client is a multi-platform GUI client that allows you to select files via drag and drop from any file manager, create the secure hash sums for each file, and submit the hash list to a list of digital notary servers. Optionally, all selected files can be backed up into a zip archive. It is written in Python and requires the wxPython toolkit.
GeneRecon 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. GeneRecon explicitly models the genealogy of a sample of the case chromosomes in the vicinity of a disease locus. Given case and control data in the form of genotype or haplotype information, it estimates a number of parameters, most importantly, the disease position.
GeneX Va is a gene expression database supporting storage and analysis of Affymetrix GeneChip technology. It is designed to serve as a secure repository and archive for many researchers' data. It is typically expected to be installed as part of a microarray center; the software is compact enough to install for a single department or even a single user. It includes an Analysis Tree package which includes an ever-expanding set of analytical tools, and has plug-in architecture allowing easy expansion. The "Va" in the name stands for the University of Virginia version, which is a total rewrite of what was originally NCGR's GeneX.
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).
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.
ImLib3D is a C++ library and visualization system for 3D (volumetric) image processing. It contains most basic image processing algorithms, as well as some more sophisticated ones. Its images are STL-compliant templated containers. It inculdes a viewer that features multiplanar views, interactive image processing, animations, vector field views, and 3D (OpenGL) multiplanar. Its main application is medical image processing.
