According to the valuable answer posted from Nodirali and the 2 web pages, please consult the following link:

http://fiehnlab.ucdavis.edu/downloads/staff/kind/Teaching/ms-chemometrics-course-9-v1.pdf

and see my added files (unfortunately in German) but you can download the software or Infos according to Tabelle 1.

You can contact Klaus Illig via Google too.

The Chembiodraw tool is for E.I. (see P.E. manual /fragmentation tool) interesting too.

Good luck
