Dear #Wile_E_Coyote, I tired almost all the way mentioned in above threads but still unable to convert .root to .txt ,
I tried [ .> dump.txt
.x dump.cxx
.> ]
and another way [ .x dump.cxx(“dump.txt”) ]
annother way [ .> dump.txt
.x dump.cxx
root -l -q dump.cxx > dump.txt ]
Thanks for your cooperation.
