Pre- and Post-processing#

Perhaps the most important part of the entire simulation process is actually plotting and processing the data that you have generated!

Tools#

There are obviously no fundamental limitations on how you can manipulate and use output files, you could even print them out and plot the points by hand if you want! Our strong recommendation would be to use Python, however – even if you think you are more comfortable with MATLAB, the open-source seismogram processing functionality exists only in Python.

Within Python, you can probably get by with ObsPy, NumPy, and SciPy. we presume that you already have NumPy and SciPy installed, you can find all the documentation needed to work with ObsPy here which includes tutorials, documentation, and worked examples.

It is worth running through some of the first few tutorials, to get you used to the language used: , , , objects, and the like.

Many supporting tools can be installed easily via conda:
