No dictionary class in singularity container

When running my executable with ROOT libraries I get the message: Warning in <TClass::Init>: no dictionary for class ROOT::TIOFeatures is available. I have never seen this error before, but my program seems to run fine and gives reasonable results, although I suspect it takes too long.
The ROOT version I am using is 6.06/08, but it is in a singularity container, so I don’t have much freedom to add or change libraries.

What does this message mean? Is it affecting to my results or computation time?

Hi,

your computation times are not affected. The root file you are reading has been created with a ROOT version which is more recent than 6.06 and forward compatibility for this case is not yet supported.

Cheers,

So this does not affect at all to my results or my code performance in general?
