Receiving a warning while trying to operate Root file

ROOT

Hi,

_ROOT Version: root_v6.26.06
_Platform: Windows 10
_Compiler: Visual Studio

When I try to open to root file with “”“root -l fileName.root”“”, I receive this error "Error in TList::Clear: A list is accessing an object already deleted (list name = TList) sequentially.

Could you help me to open root file please ?

Hi,

Welcome to the ROOT Community!
I am sorry to read that on your system this operation is not working flawlessly.
It is hard to say why given the context given. Have you tried on a more recent version of ROOT? Can you exclude the file is corrupted?

Best,
Danilo

Hi,

Thank you for your answer.

I am sure the file works properly, another person can work on it. I haven’t tried it on a recent version of ROOT. I was trying to handle this problem without reinstalling ROOT, but I guess I should do it.

Hi Mehmet,

Maybe copying the setup of the person that manages to work with the file? Sorry for not being more useful, but that could seem like a lead…

Hello,

I was the one creating the ROOT file. If it helps, it was created using the Snapshot() function of RDataframe, using ROOT v6-32-02 on lxplus. I have only checked that I am able to open it on my laptop with v6-32-00. The ROOT file only contains a TTree with simple branch types (Float_t, Bool_t, UInt_t).

We will now try to upgrade Mehmet’s ROOT version and see if it helps.

Hi,

Now, I can work on the root file. I deleted ROOT, set up WSL, and installed ROOT v6.32.02.

Thanks for your help.
