I’m doing a small project this semester using ROOT to analyze a TTree of a pPb collision. However the file I have isn’t quite what I want. A colleague has emailed me the data path of the .root file they used for a very similar project. I was wondering how to find these files from the data path given. I have a CERN account I can login to, but I don’t see where they would have all these files stored if any at all. Maybe this isn’t the place to ask this, in that case I apologize, if you could point me in the right direction that would be great.
the plugin for reading files on eos is not present in your installation.
Can you install xrootd and configure with -Dxrootd=ON (–enable-xrootd if you are not using cmake)?
Alternatively, you can use a full CMSSW stack, which includes root with all the cms environment.
So I’ve installed xrootd, gotten a CERN certificate and moved it into a .globus directory like the CERN workbook page says, I’ve connected to the grid with my lxplus account. Now I’m trying to open the file in there. Am I doing that the right way? I still can’t get anything to come up when I use the voms-proxy-init command, and when I try to open the file on the grid I’m not exactly sure what to enter in but here’s what I’ve done and this is what it has given me.
