 There are two (relevant for most) files for each run
 - `combined.root`: file with full waveform information and header information for transferred subset. These can be read with NuRadioReco.
-- `headers.root`: file with only header information (event timing, trigger information _(caveat: not currently written out by firmware, etc.)_) but for all events
