Hi all,

Would it be possible to extend manalyzer to support custom .root file names that include the run number? 

As far as I understand, the current behavior is as follows:
The default filename is ./root_output_files/output%05d.root , which can be customized by the following two command line arguments.

-Doutputdirectory: Specify output root file directory
-Ooutputfile.root: Specify output root file filename

If an output file name is specified with -O, -D is ignored, so the full path should be provided to -O. 

I am aiming to write files where the filename contains sufficient information to be unique (e.g., experiment, year, and run number). However, if I specify it with -O, this would require restarting manalyzer after every run; a scenario that I would like to avoid if possible.

Please find a suggestion of how manalyzer could be extended to introduce this functionality through an additional command line argument at
https://bitbucket.org/krieger_j/manalyzer/commits/24f25bc8fe3f066ac1dc576349eabf04d174deec

Above code would allow the following call syntax: ' ./manalyzer.exe -O/data/experiment1_%06d.root --OutputNumbered '
But note that as is, it would fail if a user specifies an incompatible format such as -Ooutput%s.root . 

So a safer, but less flexible option might be to instead have the user provide only a prefix, and then attach %05d.root in the code.

Thank you for considering these suggestions!
