This is exactly I am going to do (plus analyse outgoing parton pT) At the first sight, it is strange to see, why the MPI vertex has to be 2->2. It can not be 2->1 ? <address> if (npin == npartin && npout == npartout && npin == 2 && npartin == npartout) MPIvertices++;</address> Thank you both very much, best wishes Miro <div class="moz-cite-prefix">On 9.10.2013 13:38, Holger Schulz wrote: </div> <blockquote cite="mid:5255401A.1020507@physik.hu-berlin.de" type="cite"> <pre wrap="">On 09/10/13 11:15, Andy Buckley wrote: </pre> <blockquote type="cite"> <pre wrap="">On 09/10/13 10:59, Miroslav Myska wrote: </pre> <blockquote type="cite"> <pre wrap="">Hi Andy, could I please ask you for a help ? I would like to analyse hepmc (text) files - as a standard output from standalone H++. But I need to browse the whole generation - particles and vertices from ME and showering ... Is there a projestion in Rivet which could provide it?
