Thanks @Wile_E_Coyote
I runned the macro by using .L TBAlign.C++g and I don’t see anything on the terminal
moreover I don’t get the si-500596-trasl.root in the C:/si-calo-sep18/ directory.
About what you said TTree::MakeClass no…he didn’t wrote me about that and really I don’t know how to do the tracking reconstruction because it’s the first time… so please, if you know it, please can help me do to it? …
Thanks
