Bayesian Automated meTabolite Analyser for NMR spectra, written in the free programming language R. Like most R stuff it can be a bit programming intensive but once up and running the program deconvolutes peaks from one-dimensional NMR spectra, automatically assigns them to specific metabolites from a target list and obtains concentration estimates. The Bayesian model incorporates information on characteristic peak patterns of metabolites and is able to account for shifts in the position of peaks commonly seen in NMR spectra of biological samples. It applies a Markov chain Monte Carlo algorithm to sample from a joint posterior distribution of the model parameters and obtains concentration estimates with reduced error compared with conventional numerical integration and comparable to manual deconvolution by experienced spectroscopists. You can read more about it at the R forge site at http://batman.r-forge.r-project.org/ or in papers athttp://bioinformatics.oxfordjournals.org/content/28/15/2088.abstract andhttp://www.tandfonline.com/doi/full/10.1080/01621459.2012.695661
A powerful desktop application with a highly sophisticated graphical user interface for mapping out Baysian networks . It provides a neat “lab” environment for machine learning, knowledge modelling, diagnosis, analysis, simulation, and optimization. It is not specifically designed for metabolomics to be fair; it is for any multi-node network but since that essentially describes metabolism the kit could be very handy for metabolomics work. You can find out more about it at http://www.bayesia.com/en/products/bayesialab.php and there is a free ebook at http://www.bayesia.us/book#download that will show you more.

Chenomx HMDB database Software Update Chenomx have announced that their software is now supporting data contained within the HMDB library from the University of Alberta. Chenomx has downloaded the spectra and compound meta-data describing many of the compounds contained within the HMDB. The result is over 600 signatures that can be used within the latest Chenomx software (see http://chenomx.com/downloads/Chenomx_HMDB_Compounds.pdf). Many of these are for the same compounds that already exist within Chenomx proprietary libraries (but about half of them are not already in the Chenomx library) seehttp://chenomx.com/software/software.php?pageID=95 for info.
DEXSI Developed by Dr. Michael Dagley in Prof. Malcolm McConville‘s laboratory at The University of Melbourne, this user-friendly software, called DExSI, performs targeted automated metabolite identification, isotopologue mass (fractional labelling) and abundance determination and natural isotope abundance correction. DExSI provides a range of output options (i.e. tables, graphs and heatmaps) and is suitable for high throughput analyses. As DExSI is designed to detect metabolites irrespective of the extent of isotopic labelling, this software may also be used to perform targeted analysis on unlabelled data sets. The paper below describes new software for the targeted analysis of stable-isotope labelled data from GC-MS metabolomics experiments. The paper is available at https://academic.oup.com/bioinformatics/advance-article/doi/10.1093/bioinformatics/bty025/4816793 and the software is available at https://github.com/DExSI/DExSI/.

Elements Software for Metabolomics Elements software for metabolomics is made by Proteome Software Inc. It is based around the ideas that unlike transcripts and proteins the molecular identity of metabolites cannot be deduced from genomic information. Thus the identification and quantification of metabolites relies on sophisticated instrumentation such as mass spectrometry and nuclear magnetic resonance spectroscopy. Elements for Metabolomics is a new software tool designed to help researchers in the field of metabolomics to identify metabolites included in samples analyzed using liquid chromatography-mass spectrometry or LC-MS-MS. It has a lot of functionality in terms of data analysis. It is quite expensive but you can test it out first viahttp://www.proteomesoftware.com/products/elements/metabolomics/.

Paintomics Software Paintomics is a web tool for the integration and visualization of transcriptomics and metabolomics data. It consists of three simple steps: i) data upload: typically two data matrices, containing gene expression and metabolite levels for the same set of samples for example. ii) Metabolite assignment: specification of metabolite assignments in ambiguity cases and iii) pathway selection: pathway(s) to be painted on a two-color scheme indicating the over/under abundance of pathway elements. Currently Paintomics supports integrated visualization of about one hundred top species of different biological kingdoms and offers user the possibility to request any other organism present in the KEGG database. Please check http://www.paintomics.org/cgi-bin/main2.cgi for all the details. Users can also send a mail to firstname.lastname@example.org if they have questions on the software.

Waters Metabolomics Software
Progenesis is advanced LC-MS data analysis software that enables researchers to quantify and identify small molecule metabolites as well as larger lipids and proteins. There are two pieces of software: ‘Progenesis QI’ for small molecules and lipids and‘Progenesis QI for proteomics’ – for protein work. They both have support for all common vendor data formats and a visually guided workflow. Perhaps more interestingly, as well as conventional data-dependent analysis (DDA), Progenesis QI supports data independent analysis (DIA – http://www.medscape.com/viewarticle/814689_7). The software also takes advantage of the additional dimension of resolution offered by ion-mobility separations to give improvements in the accuracy and precision of compound identification and quantification.
