SIRIUS and CSI:FingerID are offered to the public as freely available resources. Use and re-distribution of the methods, in whole or in part, for commercial purposes requires explicit permission of the authors and explicit acknowledgment of the source material and the original publications. We ask that users who use SIRIUS and CSI:FingerID cite the corresponding papers in any resulting publications.
The CSI:FingerID web-service hosted by the boecker group at https://www.csi-fingerid.uni-jena.de, which is used by default in SIRIUS, is for non-commercial use only. For commercial users the Bright Giant GmbH provides CSI:FignerID related services that can be used with SIRIUS.
SIRIUS is a java-based software framework for discovering a landscape of de-novo identification of metabolites using single and tandem mass spectrometry. SIRIUS uses isotope pattern analysis for detecting the molecular formula and further analyses the fragmentation pattern of a compound using fragmentation trees. Fragmentation trees can be uploaded to CSI:FingerID via a web service, and results can be displayed in the SIRIUS graphical user interface. (This is also possible using the command line version of SIRIUS.) This is the recommended way of using CSI:FingerID.
Note: CANOPUS is currently NOT available for negative ion mode data and will still take some time until it will be there.

Integration of CSI:FingerID
Fragmentation trees and spectra can be directly uploaded from SIRIUS to a CSI:FingerID web service (without the need to access the CSI:FingerID website). Results are retrieved from the web service and can be displayed in the SIRIUS graphical user interface. This functionality is also available for the SIRIUS command-line tool. The training Structures of CSI:FingerID predictors are available through the CSI:FingerID WebAPI.
Training structures for positive ion mode:

Fragmentation Tree Computation
The manual interpretation of tandem mass spectra is time-consuming and non-trivial. SIRIUS analyses the fragmentation pattern resulting in hypothetical fragmentation trees in which nodes are annotated with molecular formulas of the fragments and arcs represent fragmentation events. SIRIUS allows for the automated and high-throughput analysis of small-compound MS data beyond elemental composition without requiring compound structures or a mass spectral database.
Isotope Pattern Analysis
SIRIUS deduces molecular formulas of small compounds by ranking isotope patterns from mass spectra of high resolution. After preprocessing, the output of a mass spectrometer is a list of peaks which corresponds to the masses of the sample molecules and their abundance. In principle, elemental compositions of small molecules can be identified using only accurate masses. However, even with very high mass accuracy, many formulas are obtained in higher mass regions. High resolution mass spectrometry allows us to determine the isotope pattern of sample molecule with outstanding accuracy and apply this information to identify the elemental composition of the sample molecule. SIRIUS can be downloaded either as graphical user interface (see Sirius GUI) or as command-line tool.
