Hello,

what is it you actually want to accomplish? What should be "merged" and why?

Quote:

is there a way to manually call a command for writing fOutput
to the file and emptying it halfway inside the Exec()-function?
So that I essentially generate multiple events in the output-tree
for a single Exec()-call?

I do not think it is a good Idea to work against one of the main principles of the data processing system. In- and Output files should have a 1:1 relationship - so one can use data from several root files together and be sure its the correct event each time (see 14.16.2 https://root.cern.ch/root/htmldoc/guides/users-guide/Trees.html#example- 3-adding-friends-to-trees).

I suspect your problem is somewhere else, and can be solved differently.

Jan
