A software application of RExcel that integrates R into Excel as an embedded additon for omics tasks and analysis. It can be used specifically for tasks concerning multivariate data visualization, exploration, and analysis. imDev has interactive modules for dimensional reduction, prediction, feature selection, analysis of correlation, and generation of networked structures, all of which provide an integrated environment for systems level analysis of multivariate data.

Hierarchical Clustering

R documentation for hierarchical cluster analysis on a set of dissimilarities for n objects. Each object is assigned to its own cluster, which an algorithm proceeds through iteratively. Two of the most similar clusters are joined at each stage until there is a single cluster. Distances between clusters are recomputed at each stage by the Lance–Williams dissimilarity update formula according to the particular clustering method being used. Clustering methods include: Ward's minimum variance method, complete linkage method, and single linkage method.

Glycan Mass Spectral Database (GMDB)

A multistage tandem mass spectral database using a variety of structurally defined glycans. It provides tools for glycomics research that enable users to identify glycans by spectral matching. The database stores MS2, MS3, and MS4 spectra of N-and O-linked glycans, and glycolipid glycans as well as the partial structures of these glycans.

Metabolomics Society

An independent, non-profit organization whose main goal is to promote the growth and development of the field of metabolomics internationally. They also aim to provide collaborative opportunities among scientists in metabolomics, create connections between academia, government and industry in the field of metabolomics, provide opportunities for presentation of research achievements and creation of workshops, and promote the publication of meritorious research in the field.

MetabolomeXchange

International effort whose objective is to improve and encourage the exchange of Metabolomics data. Datasets are stored in external data repositories independent of MetabolomeXchange; however, MetabolomeXchange allows users to browse datasets directly then proceed to the external repository for more information.

Eelbrain

Statistical analysis toolbox for MEG and EEG. There are three primary data-objects: Factor for categorical variables, Var for scalar variables, and NDVar for multidimensional data. Factor is a container for one-dimensional, categorial data – each case is described by a string label. Var is a container to associate one-dimensional numpy.ndarray objects with a name. NDVars offer numpy functionality that takes into account the dimensions. There is also a Dataset class which acts as a vessel for variable objects (Factor, Var and NDVar) describing the same cases.

EVidenceModeler

Software tool for automated eukaryotic gene structure annotation that reports eukaryotic gene structures as weighted consensus of all available evidence. Used to combine ab intio gene predictions and protein and transcript alignments into weighted consensus gene structures. Inputs include genome sequence, gene predictions, and alignment data (in GFF3 format).

Analysis and Annotation Tool (AAT) Package

Genome tool for analyzing and annotating large genomic sequences containing introns. It includes a program for comparing the query sequence with a protein database and another for comparing the query with a cDNA database. The database search program identifies regions of the query sequence that are similar to a database sequence. Then the alignment program constructs an optimal alignment for each region and the database sequence, as well as reports the coordinates of exons in the query sequence. Pairwise alignments of the query sequence with protein and cDNA database sequences are combined into multiple sequence alignments, which provide a view of all protein and cDNA sequences matching a query region.
