Hi Carlos, This message is printed when a Tree buffer is corrupted. This may be due to several causes -corrupted file -network problem when reading a remote file -basket compression problems with some old versions of ROOT. In principle, for these cases, you can detect a bad read by testing the number of bytes returned by TTree::getEntry or TBranch::GetEntry. If null or negative, this corresponds to a read error.
