The following information is missing from the Competing Interests section: The authors have read the journal's policy and have the following conflicts: M.L., D.S. and G.G. are inventors of the polyfunctionality index (patent number: WO2013127904) and M.L. is proprietary owner of the Funky Cells ToolBox software (www.FunkyCells.com). This does not alter adherence to all the PLOS ONE policies on sharing data and materials.
