# PyLoT
version: 0.2
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 PySide Qt4 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.
#### Prerequisites:
In order to run PyLoT you need to install:
- python 2 or 3
- scipy
- numpy
- matplotlib
- obspy
- pyside
#### 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:
- Sometimes an error might occur when using Qt
We hope to solve these with the next release.
