Create automatic workflows for yambo and quantum espresso using python. Work directly with netCDF databases. Do pre/post-processing, data analysis and plotting for yambo and quantum espresso.
- Yambo official website: http://www.yambo-code.eu/
- Yambo wiki: http://www.yambo-code.org/wiki
- Yambo Github page [download yambo & yambopy]: https://github.com/yambo-code/yambo
The main usage of yambopy is by importing its modules in the user's own scripts, such as:
from yambopy import *
from qepy import *
There is also a command line interface feature. Just type
yambopy
on terminal to see the options. Typing yambopy [option] will show the related help message.
You can find explained tutorials and a partial documentation on the Yambo wiki page: https://www.yambo-code.eu/wiki/index.php/First_steps_in_Yambopy
The tutorials contain examples scripts illustrating how to use some of the features: they are intended to be copied, modified and adapted to other use cases and to your ideas and needs.
Additional information about capabilities and usage are available inside the tutorial folder and by reading the docstrings of the various classes. Keep in mind that a basic knowledge of python (numpy and matplotlib packages) will greatly help while using yambopy.
- Create Yambo and Quantum Espresso input files from python
- Collect and manipulate the human-readable output data for analysis
- Automatic submissions of calculations (e.g., custom workflows for convergence or multi-executable runs)
- Access Yambo netCDF databases and Quantum Espresso xml files
- Analyse, interpolate and plot the results in various ways using matplotlib
- Visualize advanced quantities such as:
- dielectric function, exciton weights in k and q-space, electron-phonon matrix elements...
- Aiida plugin for Yambo-Aiida workflows
