An opensource LC-MS data processing engine


ElMaven is an open source mass spectrometry data processing engine that is optimal for isotopomer labeling and global metabolomic profiling experiments. It's designed to reduce complexity in metabolomics analysis by using an intuitive interface for exploring the experimental data. The tool aims to make research faster and easier than ever before.


Cross platform Support

MAC OS X, Linux, Windows


Open Source

Free. Personalizable. The program's code is freely available. Integrate your own data processing methods. Coding instructions are in Developer Manual



Simplified peak curation. A new feature that reimagines data visualisation to simplify your work. Track a metabolite across samples with a single visual. Visualize all peak originating from the same ion as a single group.


Automated Peak Detection

Automatically detected peaks match the gold standard of manually curated peaks by scientists with other tools. Powered by efficient algorithms for improved alignment, grouping, and annotation. Curate peaks manually in couple of hours rather than days.


Processes large datasets

Large-scale Metabolomics. Memory usage is optimized with multiprocessing to compute files larger than the system RAM. Tested for up to x00 GB.


Multiple built-in Tools

Adaptable. Ability to process both MS as well as MS/MS data from liquid and gas chromatography based mass spec experiments. The variety of widgets provide flexibility in your workflows. Perform Targeted, Untargeted, and Isotopic Analysis with a single tool.


The birth of El Maven can be traced back to another open source project, Maven, an open source LC-MS data processing engine developed by the Rabinowitz Lab at Princeton. We decided to use El Maven as the working title for the project for few reasons. One, we wanted to acknowledge the original project. We also want to commit ourselves to create “the” version of Maven that is widely used and supported by the community. Second, El bears the stamp of Elucidata.


El Maven would not have been possible without the unwavering support, constant feedback and financial support from Agios Pharmaceuticals, Inc..
