Dear all,
I have a similar problem as the one described in this ticket https://sft.its.cern.ch/jira/browse/ROOT-9884
I am trying to access files via xrootd in a TChain using TChain::Add
and get error messages [1] for files at this site root://xrootd.echo.stfc.ac.uk/lhcb:
Using TFile::Open
on them works, as well as hadd
, but calling root -l <file>
again only works for files not at root://xrootd.echo.stfc.ac.uk [2].
Here is an example file:
root://xrootd.echo.stfc.ac.uk/lhcb:user/lhcb/user/m/mstahl/2019_06/289365/289365235/SomeHyperonTuples.root
Thanks in advance for any help with the issue,
Marian
