<div><br>
</div>
<div>Thanks!</div>
<div><br>
</div>
<div>The second comment explains my situation. The colliding beams are lead nuclei, so the binary collisions can be PP, PN and NN in a heavy ion run.</div>
<div><br>
</div>
<div>Assuming simple binary collisions <span style="font-size: 13.3333px;">with an optical Glauber model</span><span style="font-size: 10pt;">, I can weigh PP, PN and NN with the geometric probability. However, it will be extremely helpful to the heavy ion
physics community if rivet can have an option for analyzing heavy ion data more easily. I appreciate the great help! </span></div>

<div dir="ltr">Hi,
<div><br>
I believe the intended behavior is this:</div>
<div><br>
</div>
<div>1) --ignore-beams won't require the beam in your hepmc file to match the beam type expected by the analysis.</div>
<div><br>
</div>
<div>2) --ignore-beams still won't allow different beam types to be analyzed in the same run, because this is usually quite a strange thing to want to do.</div>
<div><br>
</div>
<div>Unfortunately I'm not sure the "right" way to achieve what you want. Is it possible to split the events into two separate runs, one with P-P, one with P-N, and one with N-N collisions?</div>
<div><br>
