Usage Help: Calling Pysep with a specific Obspy Event

[bvanderbeek]

First, thanks for the tool! I'm sure my issue is just a new user problem.

I have an earthquake catalog (QuakeML; event_cat) and station XML file (station_inv). I'd like to download waveforms for all stations for a specific event. Additional parameters I have specified in a pysep configuration file (attached). From the documentation (specifically the last Cookbook section), I understand that this can be accomplished via:

`
#\ Dowload all waveforms for the first event in the catalog

pysep_config.yaml

sep = Pysep(inv=station_inv, event=event_cat[0], config_file='pysep_config.yaml')
sep.run()
`

However, upon calling sep.run(), I receive an error related to the event origin time (see error stack below). It appears that the event origin time being used is the null value that I have in my pysep_config.yaml. But I expected that this value would be updated given the event data I explicitly passed to pysep. I'll note that if I hand-code the event parameters into the yaml-file, the data are retrieved as expected.

Am I misunderstanding the usage or is there an additional step required to extract the event parameters?

Thanks in advance!
