Problems reading RNO-G data via the NuRadioMC-Mattak reader

[jakobhenrichs]

I downloaded and built the newest version of Mattak and tried to read some RNO-G data with the NuRadioMC-Mattak reader readRNOGDataMattak.py. For both backends, 'uproot' and 'pyroot', I get (different) errors and cannot read the data.

uproot:

pyroot:

I have no time to look into this, but my suspicious is that the problem is on the Mattak side.

Hi,

To the first (uproot) problem seems to be related with the sampling rate being None in the mattak "file" (or rather being set to None during read-out if it was not stored or could be read). If you checkout this branch (https://github.com/nu-radio/NuRadioMC/pull/531) you should get a more meaningful error message. I also added the overwrite_sampling_rate which allows you to set the sampling rate by hand and read these "broken" files.

To the second (pyroot) problem: This indeed seems to be a NuRadioMC issue, let me see if I can reproduce and fix it

Alright, the second issue should be fixed with the newest commit in https://github.com/nu-radio/NuRadioMC/pull/531

LMK if you get any other problem

Thank you! Using the newest commit (https://github.com/nu-radio/NuRadioMC/pull/531) reading data with both backends works.
