Based on the R package of the same name, web interface for calculating isotope patterns (fine structure), profiles, centroids and intensoids. Resolves isotopic fine structures even for large molecules. Allows usage of build-in instrument resolutions, predefined or user-defined adducts and batch processing. Best viewed with Firefox, Google Chrome and Safari. 

R tool for grouping of isotopes and adducts to components as well as detection of homologue series out of high resolution mass spectrometer data sets.

R tool for batch-processing, recalibration and cleanup of HRMS spectra and MassBank record generation.

RMassBank is a workflow to enable the creation of high quality accurate mass MS/MS spectral records for the MassBank database. The workflow includes automatic recalibration and processing of mass spectra within R from mzML files and the retrieval of compound information via web services to minimise the user efforts in record generation. At this stage RMassBank is designed and tested on Orbitrap XL (Thermo) data. For more information please contact Emma Schymanski.

Example data for RMassBank (raw data files, ~50 MB)

Partitioning, EIC clustering and peak detection for baseline-corrected and centroided LC-HRMS data in mzXML format. Interactive result and raw data viewer, batch processing & browser-based UI.

Assessment tool for OECD 308 experiments

A command-line utility for the inverse modelling of OECD 308 experiments with Bayesian parameter inference.
