Include the following information in your bug report:

1. The command line (i.e. call) including the TOPP tool and the arguments you used, or the steps you followed in a GUI tool (e.g. TOPPView) - e.g. FeatureFinderCentroided -in myfile.mzML -out myfile.featureXML.

2. The output of OpenMS/TOPP (or a screenshot in case of a GUI problem).

3. Operating system (e.g. “Windows XP 32 bit”, “Win 7 64 bit”, “Fedora 8 32 bit”, “macOS 10.6 64 bit”).

4. OpenMS version (e.g. “OpenMS 1.11.1”, “Revision 63082 from the SVN repository”).
