Installation

There are two way to install/run pyFlightAnalysis.

Run from Source

pyFlightAnalysis is based on: pyqtgraph (which is based on PyQt), pyOpenGL, pyulog, and a number of other widely used scientific packages including numpy, matplotlib, etc. Once you have installed these package you can download and run the source file:

>>> # In folder where you want put the source code
>>> git clone https://github.com/Marxlp/pyFlightAnalysis.git
>>> cd pyFlightAnalysis/src
>>> python analysis.py

Install and Run

PyQt4 can't directly be installed using pip so you need to install it manually (if using Anaconda, install using the command: conda install pyqt). PyQt5 installs directly from pip, but only supports Python 3.x.

After installing PyQt do:

>>> # Install from pypi
>>> pip install pyFlightAnalysis

>>> # or install from source
>>> git clone https://github.com/Marxlp/pyFlightAnalysis.git
>>> python setup.py install

>>> # then run it
>>> analysis
