pySW4 is an open-source project dedicated to provide a Python framework for working with numerical simulations of seismic-wave propagation with SW4 in all phases of the task. Preprocessing, post-processing and runtime visualization. It also provides several other tools for handling GeoTIFF files such as ASTER-GDEM tiles and others, plotting shaded-relief DEM maps and draping data over them, creating movies from image sequences, etc.
The functionality is provided through 5 sub-packages which include pre- and post-processing routines including the rfileIO library for interaction, reading and writing seismic models in the rfile format.
There are some useful utilities for geodesic projections of data and for reading and writing GeoTIFF files.
In the command line interface scripts, there are some quick and dirty plotting routines which can be run from the command line. It may be useful to run these scripts on the server-end while the computation is running in order to generate pseudo-RunTime visualization of the results.
See the full API documentation page and Tutorial examples.
conda
Installing pySW4 from the conda-forge channel can be achieved by
adding conda-forge to your channels with:
$ conda config --add channels conda-forge
Once the conda-forge channel has been enabled, pySW4 can be
installed with:
$ conda install pysw4
It is possible to list all of the versions of pySW4 available on
your platform with:
$ conda search pysw4 --channel conda-forge
pip
You can install the repository directly from GitHub. Use this command to install from master:
$ pip install https://github.com/shaharkadmiel/pySW4/archive/master.zip
To get the latest release version do::
$ pip install https://github.com/shaharkadmiel/pySW4/archive/v0.3.0.zip
Add the --no-deps to forgo dependency upgrade ot downgrade.
Plots and movies for a SW4 simulation run can be created using the
pySW4-create-plots command line utility, e.g.:
$ pySW4-create-plots -c /tmp/UH_01_simplemost.in -s UH1 -s UH2 -s UH3 \\
--pre-filt 0.05,0.1,100,200 --filter type=lowpass,freq=10,corners=4 \\
