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.

1. MSP file
MSP file created using Create MSP tool
2. Select SIRIUS-CSI:FingerID Databases
The following databases are available:
3. Mass deviation of the fragment peaks in ppm
Allowed mass deviation of the fragment peaks.
4. The maximum number of candidates in the output
Set the top X candidates to return.
5. Ion mode
6. Analysis used
If you want to analyze spectra measured with Orbitrap or FT-ICR, you should specify the appropriate analysis profile. A profile is a set of configuration options and scoring functions SIRIUS 3 will use for its analysis. For example, the Orbitrap and FT-ICR profiles have tighter constraints for the allowed mass deviation but do not rely so much on the intensity of isotope peaks.
