Looping over .dat files with several variables and convert them into ROOT files with separate Branches in a single TTree

[panema]

Hello All,

I have 180 .dat files containing 13 different variables for up to 3000000 events. I would like to convert them into ROOT files with 13 different Branches for each variable. First of all, I have to make a loop to read all the 180 .dat files. Then, I have to convert them into root files and fill the Tree. I already know how to create the Branches and the Tree, but not a specific idea for the loop over the dat files and also how to fill the tree. Any help would be really appreciated.
