Hi

Have you given the full correct path of your data sample. Also given the LHE event file you are running ma5 in particle mode right?

> MA5-ERROR: command root-config is not found
When you launch ma5 it tells you what it can see and what it can not see. Do you see rood as active there?

I'm sorry I'm quite new to Madanalysis. How do I give the full correct path of my data sample? And how do I know if I'm running in particle mode?

It says that rott is disabled.

Firstly you can go through our tutorials and manual to see how MadAnalysis works. When you do anything in your computer you need to give the location of a file otherwise the program wont be able to find it just like in any other terminal based program you can type the exact path of your sample.

ma5> import /PATH/TO/MY/SAMPLE/my_sample.lhe.gz

run in particle mode: $ ./bin/ma5

I was running in particle mode.

But even when I path the way It says this:

ma5>import samples/downloads/proc_sm_1/events/run_01/unweighted_events.lhe.gz

MA5-ERROR: The dataset 'samples/downloads/proc_sm_1/events/run_01/unweighted_events.lhe.gz' has not been found or has a unsupported format.

Can Ma5 see your zlib libraries if not you need to install it.

I installed zlib and now it can see ROOT but it says that gnuplot is disabled. Is that also something I need to download? Because I still get this error:

ma5>import samples/downloads/proc_sm_1/events/run_01/unweighted_events.lhe.gz

MA5-ERROR: The dataset 'samples/downloads/proc_sm_1/events/run_01/unweighted_events.lhe.gz' has not been found or has a unsupported format.

This has nothing to do with root or gnuplot, if you read the manual you will see that those are only relevant for plotting and/or when you use delphes. MadAnalysis assumes that the relative path starts from madanalysis main folder, is your samples folder under madanalysis main folder?

Yes, I have placed the file in the samples folder which is in the main MadAnalysis folder. But I still get the same error.

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

Can you please try with the absolute path to the sample?

Cheers,

Benjamin

Sorry for the delay.
