Re: [ROOT] Error message from TChain::GetEntry()

Hi again,

there are also error messages of the type:

Warning in <TBasket::ReadBasketBuffers>: basket: has fNevBuf=0, but 
fEntryOffset=0, trying to repair

After that everything seems to be fine. I am just wondering if "trying to 
repair" means that it was successfull to repair the file or not.
