comments: I am going to learn how to access ATLAS AOD MC and Data files

copied one MC aod file at
/susyraid1/home/jkim/AOD.122124._000491.pool.root

when I open the aod file using root, I got warning messages starting with
Warning in <TClass::TClass>: no dictionary for class DataHeader_p5 is available

errors when opening an library file
root [0] .L $ROOTSYS/lib/libPhysics.so
dlopen error: /susyraid1/opt/physics/root_v5.26.00e/lib/libPhysics.so: undefined symbol: _ZTV11TDecompChol
Load Error: Failed to load Dynamic link library /susyraid1/opt/physics/root_v5.26.00e/lib/libPhysics.so
* Interpreter error recovered ***
