Dear All,
I get hard time to understand the class TEntryListFromFile. I maybe need some help… 
More precisely I am using TChain to add a list of files as following:
TChain *ch = new TChain("mytree");
ch->Add("./hist-*.root");
In my current directory ./ there are files named :
[quote]hist-263260.root
hist-263265.root
hist-263266.root
[…]
hist-263291.root
hist-263292.root
hist-263293.root
hist-263294.root[/quote]
According to the documentation and some threads in this forum, I understood that I should create files named as following : hist-XXX_elist.root
So I put my entrylists here : ./elist1/hist-XXX_elist.root
Then I would like to load the correct elist files using TChain::SetEntryListFromFile(); according to the wildcard that I use to load my TChain. Sometimes, I have to use something similar to the following wildcard : “hist-26329*.root”. So I would only load the hist-26329*_elist.root.
So to simplify everything I first would like to work with only one rootfile.
So, I used the following code :
TChain *ch = new TChain("mytree");
ch->Add("./hist-263294.root");
ch->SetEntryListFromFile("elist1/hist-263294_elist.root");
In the documentation they are referring to the function SetEntryList, but it mess up when I try to use it.
At this moment I only get this message :
I checked my EntryList it contains events, I used it manually by myself!
Do I correctly understand the situation ? Someone could help me to solve my problem ?
Thank you very much !
