Weighbor, DigitalGenome


Bill Bruno of Los Alamos National Lab and colleagues have released version 1.2 of Weighbor, a free program for reconstructing phylogenetic trees from sequence data, at

Weighbor is a weighted version of neighbor joining that gives less weight to the longer distances in the distance matrix. The program is Phylip compatible. C source code and a Linux executable are available.


MolecularWare of Cambridge, Mass., has launched its DigitalGenome suite of data management software products.

DigitalGenome allows users to automatically receive large amounts of data from various high-throughput instruments, such as liquid handling robots, microarraying robots, and microarray scanners. Once the data is captured, it can be cleansed, archived, stored in functional frameworks, and mined.

MolecularWare said it has also signed on the Whitehead Institute for Biomedical Research as its first US-based DigitalGenome customer and has begun shipping the product.
