Error when I try to process my seismological data


i hope that you are fine

I am writing to tell you about the error that I present when trying to process my seismological data.
i have my station.xml, my waveform in miniSEED and i have my “events-mars.xml”, so i dont know what is the problem.

ERROR   cannot read events/stations or initalize data

I must tell you that my data comes from the seismometer of the insight mission on mars.

thanks for your help

This error is the result of no matching information in your file that matches the QuakeML format line: r'^{([^}]*))}quakeml' - it looks like your file is not QuakeML formatted. It might be worth checking that you are providing a QuakeML file.
