I got the same issue. It can be reproduced with [these waveform data](https://gist.github.com/Brtle/6776fd37925b7fb87375cceb24517652/raw/f429dffd33962ee011f09d974056eaada0382760/ar_picker.mseed). My test script looks like this: ```python #! /usr/bin/env python3 from obspy.core import read from obspy.signal.trigger import...

> #2184 raises an error so it will "fix" the issue from @Brtle's example. I agree that arrays must have identical sizes but I don't think it solves the problem....

I indeed want to recompute the magnitudes. My script looks like: ```python ep = DataModel.EventParameters() DataModel.Notifier.Enable() if self.remove_magnitudes is not None: self._remove_magnitudes(origin) if self.remove_amplitudes is not None: self._remove_amplitudes(ep, origin) DataModel.Notifier.Create(ep,...
