SIRIUS 4.0.1 released

A new version of SIRIUS 4 is available for download.
SIRIUS 4.0.1 brings many bugfixes, user interface polishing and improved stability of the CSI:FingerID backend.

See our changelog for further details .

You can download SIRIUS with CSI:FingerID here.

SIRIUS 3 is not longer supported

We found a major bug in the web service of SIRIUS 3 which can also affect the stability of the new SIRIUS 4. Therefore we decided to shut down the web service of SIRIUS 3 immediately.

Please contact us () if you need to finish work that can only be done with SIRIUS 3. We will try to find a solution then.


SIRIUS+CSI:FingerID is no available for Mac. You can download it here. A few highlights of the new version:

  • Searching your tandem mass spectra in molecular databases using CSI:FingerId
  • Restrict the SIRIUS molecular formula identification to formulas appearing in molecular databases – or search through the whole space of possible formulas. It’s up to you.
  • Sort you identification results by confidence such that more reliable identifications (e.g. from high quality spectra or easy recognizable compounds) are separated from bogus identifications.
  • Predict structural features and substructures from tandem mass spectra and visualize them in your candidate structure list.

Don’t hesitate to give us your feedback, report bugs or suggesting new features. Just write to

Gastvorlesung Ivo Große

Ivo Große von der Universität Halle wird uns am 13. Januar besuchen und eine Gastvorlesung zum Thema Motif Finding und EM-Algorithmus halten – klassische Themen der Bioinformatik, die in Jena leider nicht mehr gelehrt werden.

Die Vorlesung findet am Mittwoch den 13. Januar von 9:30 bis 12:00 Uhr im Seminarraum 119, August-Bebel-Str. 4 statt.

Die Veranstaltung ist für alle Studierenden der Bioinformatik, insbesondere für alle Master-Studenten interessant. Alle Interessierten sind herzlich eingeladen.
