Hello! does anyone know the answers to the following: 1) Open an existing root file containing a tree with a single branch in a completely different file to the one it was made(easy). Then add additional variables to this branch which are simple doubles and ints without overwriting the original branch. If this is possible, are the additional variables stored at the entry number where it finished last time or start from scratch. If (1) is impossible then I may fill the tree with dummy leaves so that I simply update vertically. 2) Could someone give an example of how to append entry's to a tree. Thanks in advance Martin.
