How is everyone doing with the little ROOT challenge exercise? Were you able to identify the hidden resonance?
There is one of you who has already made quite some progress and is almost finished with it!
Please keep me updated and/or send me any interesting plots you may have.
Does anyone remember/know the exact difference between “Row” and “Instance”? Is “Instance” the event number in one run? I don’t really understand the terminology.
I have difficulty opening the muons.root file and the macros file. For the macros file: if I use wget in the linux terminal it says “authorization failed”. If I try to copy the code into an emacs file and then move it to the root/macros directory so that I can access it in root, it does not work either. It says permission denied.
In addition, I can only open muons.root by clicking on it, which brings up root with the file in it. This is fine, but I need to be able to access the macros file or any .C file I create too. Can anyone help?
So I am having problems opening ROOT in lxplus. If I just call ROOT by typing “root” it says that the command isn’t found even though I am in the right directory and I have ROOT in there. I have tried typing “./root &” since that is how I open ispy in lxplus but that says Permission Denied. I have tried “chmod +x root” but it doesn’t change anything. Do you know what I am doing wrong? I am probably making a simple mistake since I don’t know many linux commands.
I was working on trying to figure out which muons are the hardest muons. Are the hardest muons the ones with the most energy? I scanned “mu_e”, but I can’t tell which muons have the highest energy because it seems scattered throughout the events.. I’m not sure if what I said makes sense.. I also thought that if I drew “mu_e” it would help me figure out which muons had the highest energy, but it plots the number of muons that had a particular energy, not which muon had what energy..right?
I’m aware that there is a GetMaximum function in TTree, but it won’t tell us which event produced the maximum energy..so will that help us?
I just realized I left a lecture off of our schedule for classes at UniGe. Sorry about this! I corrected the schedule. There IS a QM class Wednesday evening from 4-6pm Which makes me worry about conflicts with the computing class from 2-4 on Wednesdays. I am very sorry about this.
Elim and I cannot get our presentation to appear on the website even using her MAC. We are not sure what is going on. Also I emailed Guoan again because Vista still has problems doing this.
