# PyLoT
|
|
|
|
version: 0.3
|
|
|
|
The Python picking and Localisation Tool
|
|
|
|
This python library contains a graphical user interfaces for picking seismic phases. This software needs [ObsPy][ObsPy]
|
|
and the PySide2 Qt5 bindings for python to be installed first.
|
|
|
|
PILOT has originally been developed in Mathworks' MatLab. In order to distribute PILOT without facing portability
|
|
problems, it has been decided to redevelop the software package in Python. The great work of the ObsPy group allows easy
|
|
handling of a bunch of seismic data and PyLoT will benefit a lot compared to the former MatLab version.
|
|
|
|
The development of PyLoT is part of the joint research project MAGS2 and AlpArray.
|
|
|
|
## Installation
|
|
|
|
At the moment there is no automatic installation procedure available for PyLoT. Best way to install is to clone the
|
|
repository and add the path to your Python path.
|
|
|
|
It is highly recommended to use Anaconda for a simple creation of a Python installation using either the *pylot.yml* or the *requirements.txt* file found in the PyLoT root directory. First make sure that the *conda-forge* channel is available in your Anaconda installation:
|
|
|
|
conda config --add channels conda-forge
|
|
|
|
Afterwards run (from the PyLoT main directory where the files *requirements.txt* and *pylot.yml* are located)
|
|
|
|
conda env create -f pylot.yml
|
|
or
|
|
|
|
conda create --name pylot_38 --file requirements.txt
|
|
|
|
to create a new Anaconda environment called "pylot_38".
|
|
|
|
Afterwards activate the environment by typing
|
|
|
|
conda activate pylot_38
|
|
|
|
#### Prerequisites:
|
|
|
|
In order to run PyLoT you need to install:
|
|
|
|
- Python 3
|
|
- obspy
|
|
- pyside2
|
|
- pyqtgraph
|
|
- cartopy
|
|
|
|
(the following are already dependencies of the above packages):
|
|
- scipy
|
|
- numpy
|
|
- matplotlib <= 3.3.x
|
|
|
|
#### Some handwork:
|
|
|
|
PyLoT needs a properties folder on your system to work. It should be situated in your home directory
|
|
(on Windows usually C:/Users/*username*):
|
|
|
|
mkdir ~/.pylot
|
|
|
|
In the next step you have to copy some files to this directory:
|
|
|
|
*for local distance seismicity*
|
|
|
|
cp path-to-pylot/inputs/pylot_local.in ~/.pylot/pylot.in
|
|
|
|
*for regional distance seismicity*
|
|
|
|
cp path-to-pylot/inputs/pylot_regional.in ~/.pylot/pylot.in
|
|
|
|
*for global distance seismicity*
|
|
|
|
cp path-to-pylot/inputs/pylot_global.in ~/.pylot/pylot.in
|
|
|
|
and some extra information on error estimates (just needed for reading old PILOT data) and the Richter magnitude scaling
|
|
relation
|
|
|
|
cp path-to-pylot/inputs/PILOT_TimeErrors.in path-to-pylot/inputs/richter_scaling.data ~/.pylot/
|
|
|
|
You may need to do some modifications to these files. Especially folder names should be reviewed.
|
|
|
|
PyLoT has been tested on Mac OSX (10.11), Debian Linux 8 and on Windows 10.
|
|
|
|
## Release notes
|
|
|
|
#### Features:
|
|
|
|
- event organisation in project files and waveform visualisation
|
|
- consistent manual phase picking through predefined SNR dependant zoom level
|
|
- consistent automatic phase picking routines using Higher Order Statistics, AIC and Autoregression
|
|
- interactive tuning of auto-pick parameters
|
|
- uniform uncertainty estimation from waveform's properties for automatic and manual picks
|
|
- pdf representation and comparison of picks taking the uncertainty intrinsically into account
|
|
- Richter and moment magnitude estimation
|
|
- location determination with external installation of [NonLinLoc](http://alomax.free.fr/nlloc/index.html)
|
|
|
|
#### Known issues:
|
|
|
|
We hope to solve these with the next release.
