Baran R, Kochi H, Saito N, Suematsu M, Soga T, Nishioka T, Robert M, Tomita M. MathDAMP: a package for differential analysis of metabolite profiles. [BMC Bioinformatics 2006, 7:530]: Describes a software package called MathDAMP (Mathematica package for Differential Analysis of Metabolite Profiles), which highlights differences between raw mass spec datasets analyzing corresponding signal intensities “on a datapoint-by-datapoint basis” in order to bypass peak identification and integration, the authors note.
Eronen L, Geerts F, Toivonen H. HaploRec: Efficient and accurate large-scale reconstruction of haplotypes. [BMC Bioinformatics 2006, 7:542]: Describes three statistical models and an algorithm for haplotype reconstruction, jointly called HaploRec. HaploRec uses “local regularities” in order to reconstruct haplotypes so that they have maximal local coherence, the authors note in the paper’s abstract.

Good BM, Kawas EA, Kuo BY, Wilkinson MD. iHOPerator: User-scripting a personalized bioinformatics Web, starting with the iHOP website. [BMC Bioinformatics 2006, 7:534]: Describes an effort to enhance the content and presentation of the iHOP (information Hyperlinked Over Proteins) website using the GreaseMonkey Firefox extension for developing and deploying user scripts. The iHOPerator user script “augments the gene-centered pages on iHOP by providing a compact, configurable visualization of the defining information for each gene and by enabling additional data, such as biochemical pathway diagrams, to be collected automatically from third party resources and displayed in the same browsing context,” the authors note in the paper’s abstract.
Hua J, Craig DW, Brun M, Webster J, Zismann V, Tembe W, Joshipura K, Huentelman MJ, Dougherty ER, Stephan DA. SNiPer-HD: improved genotype calling accuracy by an expectation-maximization algorithm for high-density SNP arrays. [Bioinformatics 2007 23(1):57-63]: Introduces a SNP genotype-calling program called SNiPer-High Density for calling genotypes across hundreds of thousands of SNPs. The program uses an expectation-maximization algorithm with parameters based on a training sample set. The method also uses a quality-control metric for each assayed SNP, so that “poor-behaving” SNPs can be filtered, the authors note in the abstract.

[Nucleic Acids Research 2006 34(22):6605-6611]: Describes a software package for designing degenerate primers for large groups of related targets based on complex multiple sequence alignments. The method is based on tree building followed by a set-covering algorithm.
Jenett A, Schindelin JE, Heisenberg M. The Virtual Insect Brain Protocol: creating and comparing standardized neuroanatomy. [BMC Bioinformatics 2006, 7:544]: Describes the Virtual Insect Brain protocol, a script suite for the quantitative assessment, comparison, and presentation of neuroanatomical data. The suite is based on the 3D-reconstruction and visualization software Amira from Mercury. The protocol has been developed for standardizing Drosophila neuroanatomy, but it can also be used for other 3D structures, the authors note. Availability: http://www.neurofly.de/.

[BMC Bioinformatics. 2006 Dec 1;7:525]: Describes a system for analyzing HapMap data in order to characterize the haplotype structure of genes or chromosomal regions. The system, called iHAP, includes genotype and haplotype data from the HapMap project and gene information from the UCSC Genome Browser Database, as well as capabilities for inferring haplotype blocks and selecting tag SNPs that are representative of haplotype patterns.
