TStreamerInfo warnings

[Ailema]

Hello,

I am running locally my analysis code and I get this error:

W-TStreamerInfo::BuildCheck: 
   The StreamerInfo for version 4 of class AliMC read from the file ~/galice.root
   has a different checksum than the previously loaded StreamerInfo.
   Reading objects of type AliMC from the file ~/galice.root 
   (and potentially other files) might not work correctly.
   Most likely the version number of the class was not properly
   updated [See ClassDef(AliMC,4)].
W-TStreamerInfo::CompareContent: The following data member of
the on-file layout version 4 of class 'AliMC' differs from 
the in-memory layout version 4:
   float fRDecayMax; //
vs
   float fPuRmax; //
W-TStreamerInfo::CompareContent: The following data member of
the on-file layout version 4 of class 'AliMC' differs from 
the in-memory layout version 4:
   float fRDecayMin; //
.
.
.

This configuration is used for running locally:
ROOT/v6-20-08
Can you please help me solve this problem?

Thank you.

Hi,
This is usually happen when you are using different software version for writing and reading data.
It seems that the AliROOT team changed the structure of file but not the ClassDef version.
Maybe update of AliROOT should help?
