A free and open source GUI toolkit for DNA editing - written in python

This project aims to provide a powerful codebase for viewing, editing and creating DNA in the GenBank format. The code is free to use, modify and re-distribute under a GPL license. Contributions in the form of improvements and new functions are welcome and encouraged!

The software is being developed on a Linux machine and works well in that environment. As the software matures testing will start on Windows and Mac to make sure it is cross-platform. The only external library that is needed is wxPython. Launch main.py to give the software a go (it is still under heavy development though).

To start testing the software you have to install python, wxpython and pycairo:

sudo apt-get install python2.7 python-wxgtk2.8 python-cairo

Then you can download the software and run it:

cd ~
git clone https://github.com/mengqvist/DNApy.git
cd DNApy
python main.py

On Ubuntu 15.04 the following message might occure:

/usr/bin/xsel
Segmentation fault (core dumped)

This can be resolved by additionaly installing the package xclip:

sudo apt-get install xclip
