Hi Andy
<div><br>
</div>
<div>to print to HepMC in a readable format is very essential</div>
<div>for people trying to learn what the MC is doing and to understand</div>
<div>how to do a selection for the analysis, also using Rivet just for</div>
<div>MC studies.</div>
<div><br>
</div>
<div>We have now several summerstudents, who use Rivet as an interface</div>
<div>to the MCs and to perform different studies. For this an understanding of</div>
<div>the event record is important.</div>
<div><br>
</div>
<div>Anyway, as I send yesterday in my mail, we have now managed to print</div>
<div>the HepMC record in a readable format in Rivet, so this is fine now.</div>
<div>Maybe it could be of help also for others to have this option available.</div>
<div><br>
</div>
<div>Cheers</div>

<div>Hi Hannes,<br>
<br>
Why on earth would Rivet have a "print event like PYTHIA" function? The<br>
access to the GenEvent object with all the structure is one function<br>
call away from Rivet::Event -- is that really "complicated and difficult"?!<br>
<br>
We've tried to provide nicer ways than HepMC itself to access event<br>
details -- iterating over particles, for example, is far easier than in<br>
native HepMC. But our emphasis is on the histogrammed output more than<br>
what's printed out to the terminal... and far more on the final state<br>
and hadron relationships than the internal HepMC structure.<br>
<br>
Other than the HepMC print and IO_AsciiParticles functions (and reading<br>
the ASCII format), there are also a few graphical visualisation tools,<br>
e.g. mcviz, that might be of interest.<br>
<br>
Cheers,<br>
Andy<br>
