<div dir="ltr">Dear Shaoqi,<div><br></div><div>I have been forwarded the email discussion you had with Prof. Issever on the BlackMax issue you have encountered. Could you please tell me which option are you using to compile BlackMax (BlackMaxOnly, BlackMax or all) and the Pythia version you are using? Using the same parameter.txt file you sent Prof. Issever I can generate events just fine by compiling in the BlackMax mode, so I guess the problem might be with Pythia if you are using the all compilation mode.</div><div><br></div><div>Best,</div><div><br>Marc</div></div><div class="gmail_extra"><br><div class="gmail_quote">On 3 March 2015 at 14:50, Marc Cano Bret <span dir="ltr"><<a href="mailto:marc.bret.87@gmail.com" target="_blank">marc.bret.87@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Hi Cigdem,<div><br>Looking through the output file and the parameter.txt I don't see anything striking. I have run BlackMax myself using his file and don't get any errors. I first ran with the CTEQ PDF and then with the PDF he is using (21000, which is MSTW2008). It is then quite possible that this is a Pythia issue. I normally compile BlackMax with the BlackMaxOnly or BlackMax choice so I haven't encountered this problem. The Pythia version I have in my computer (8.175) is very recent and BlackMax doesnt compile with that one. We should ask which option he is using to compile BlackMax and if he is using the Pythia version mentioned in the README file. I will drop him an email. </div><div><br></div><div>Best,</div><div><br>Marc</div></div><div class="HOEnZb"><div class="h5"><div class="gmail_extra"><br><div class="gmail_quote">On 3 March 2015 at 14:18, Cigdem Issever <span dir="ltr"><<a href="mailto:c.Issever1@physics.ox.ac.uk" target="_blank">c.Issever1@physics.ox.ac.uk</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> <div> <div style="direction:ltr;font-family:Tahoma;color:#000080;font-size:10pt">and the outputs<span><br> <div><br> <div style="font-size:13px;font-family:Tahoma"> <div style="font-size:13px;font-family:Tahoma"> <div style="font-size:13px;font-family:Tahoma"> <div style="font-size:13px;font-family:Tahoma"> <div style="font-size:13px;font-family:Tahoma"> <div style="font-size:13px;font-family:Tahoma"> <div style="font-size:13px;font-family:Tahoma"><font color="#008000">---------------------------------------------------------------------<br> <a href="https://www2.physics.ox.ac.uk/contacts/people/issever" target="_blank">Cigdem Issever</a> <font color="#008000"> </font> <br> University of Oxford </font><font color="#008000"><font color="#008000">@ CERN office 104/1-C14</font> <br> Skype-id: cigdem.issever Oxford Tel: <a href="tel:%2B44-1865-273337" value="+441865273337" target="_blank">+44-1865-273337</a> <br> ---------------------------------------------------------------------</font><br> </div> </div> </div> </div> </div> </div> </div> </div> </span><div style="font-family:Times New Roman;color:#000000;font-size:16px"> <hr> <div style="direction:ltr"><font face="Tahoma" color="#000000"><b>From:</b> Shaoqi Hou [<a href="mailto:shou@crimson.ua.edu" target="_blank">shou@crimson.ua.edu</a>]<br> <b>Sent:</b> 25 February 2015 15:57<br> <b>To:</b> Cigdem Issever<br> <b>Cc:</b> Email the developers<span><br> <b>Subject:</b> Re: [Blackmax] Running BlackMax at 8 TeV failed<br> </span></font><br> </div> <div></div> <div> <div dir="ltr"> <div> <div> <div>Hi Prof. Issever,<br> <br> I ran BlackMax with the newest parameter.txt sent to you.
