I’ve been happily working with CSS format files generated by the Pisces package but have a small if frustrating to figure out issue when trying to read them with ObsPy. Essentially, I get an unknown file format error using ‘read’ unless I specify what the data format is explicitly, i.e., st = read(“file.wfdisc”, format = “CSS”). Specifically the error is:
~/anaconda3/lib/python3.6/site-packages/obspy/core/util/base.py in _read_from_plugin(plugin_type, filename, format, **kwargs)
–> 392 raise TypeError(‘Unknown format for file %s’ % filename)
394 # format given via argument
TypeError: Unknown format for file /dir/file.wfdisc
It seems the automatic file type detection isn’t working, something I note was in a thread about 3 years ago (http://lists.swapbytes.de/archives/obspy-users/2015-February/001642.html). However, I’m not sure if this is ObsPy related, or Pisces related and whether it’s worth opening an Issue on the GitHub site.
I could make a small test data example if needed.
Thanks for any comments.
