Couldn't write catalog object to QuakeML

[okling]

Hi Kasra,

I had an issue in writing event catalog (Quake ML) after updating Obspy.

I was trying to download waveforms using the following command:

obspyDMT --datapath Alaska_M6.5 --min_date 2018-08-14 --max_date 2018-08-16 --sta="*" --net="BW" --station_rect="1/22/40/52" --loc "*" --cha "HHZ" --event_rect="-180/-160/45/55" --min_mag 6.0 --preset 0 --offset 7200 --sampling_rate 20 --instrument_correction --corr_unit "DIS" --pre_filt "0.001, 0.005, 10, 20" --data_source all --event_catalog "NEIC_USGS" --req_parallel 

But I received this error message and no ML file was written in the EVENT-INFO folder:

Here are my current packages:

python                    3.7.3                h5b0a415_0    conda-forge
obspy                     1.2.1            py37h03ebfcd_1    conda-forge

basemap-data-hires        1.2.1                         0    conda-forge

The data set cannot be updated (e.g. adding more stations/channels). Any ideas on this? Thanks for your help!

Cheers,
Angel

Hi Angel, Could you please try the new version of obspyDMT (2.2.7). Indeed, there were some inconsistencies between obspyDMT and the latest version of obspy. Thank you for reporting this.

Hi Kasra, thanks for the quick response! It is fixed in the master branch, but it is not fixed in the routing_client branch, which has the option --eida_token_path. In the master branch, it gives this message: obspyDMT: error: no such option: --eida_token_path. Could you implement this option to the master branch or also resolve the compatibility in the routing_client branch?

Thanks again!

Hi Kasra, I have found another problem with writing QuakeML catalog even in the master branch. So instead of a ML catalog catalog.ml in the EVENTS-INFO folder, a file called catalog.ml.pkl is written. When I'm trying to open (pickle) it, it gives me the following message:

>>> import obspy
>>> import pickle
>>> ev_load = open("catalog.ml.pkl","r")
>>> ev_pkl = pickle.load(ev_load)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/aling/anaconda3/envs/obspy/lib/python3.7/codecs.py", line 322, in decode
    (result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0x80 in position 0: invalid start byte

If reading in binary,

>>> ev_load = open("catalog.ml.pkl","rb")
>>> ev_pkl = pickle.load(ev_load)
