[MSNoise] Some little things and one question about data from more than one network.

[Kasper van Wijk]

Tom, as you suggested, the problem may be bigger than file names/ networks.
Here's the output after changing to the NZ network name of our extra
station to match that of the rest of the stations. Both are mseed data
types:

Traceback (most recent call last):
