Reading

Reading CyberShake waveform data is handled by using ObsPy’s standard read() function. The format is detected automatically.

>>> from obspy import read
>>> st = read("/path/to/test.grm")
>>> st 
<obspy.core.stream.Stream object at 0x...>
>>> print(st)  
2 Trace(s) in Stream:
CS.USC.00.MXE | 1970-01-01T00:00:00.000000Z - ... | 20.0 Hz, 8000 samples
CS.USC.00.MXN | 1970-01-01T00:00:00.000000Z - ... | 20.0 Hz, 8000 samples
>>> print(st[0].stats)

CyberShake specific metadata is stored in stats.cybershake.

>>> for k, v in sorted(st[0].stats.cybershake.items()):
...     print("'%s': %s" % (k, str(v))) 
    'det_max_freq': 1.0
    'rup_var_id': 144
    'rupture_id': 0
    'source_id': 12
    'stoch_max_freq': -1.0
