Hi everyone,
I am relatively new to using ObsPy and I have run into a problem that I can’t seem to figure out on my own. I am trying to analyze some seismic data from a local network…, specifically focusing on filtering and plotting the waveforms.
I have followed the basic tutorials…, but I am getting unexpected results when I apply the filters my waveforms seem distorted and the signal looks almost entirely different after filtering.
Here’s a quick rundown of what I’m doing:
- Reading the data using
read(). - Applying a bandpass filter with
filter('bandpass', freqmin=1.0, freqmax=10.0). - Plotting the waveform with
plot().
Has anyone encountered similar issues or can point out what I might be doing wrong: ??
Any tips on best practices for filtering seismic data using ObsPy would also be really appreciated…! 
I have also read this thread https://discourse.obspy.org/t/help-needed-for-continuous-seismic-data-downloads-with-obspy-react-native/1709 but couldn’t get any solution related to my query.
Thanks in advance for your help…!
