UVVisPy documentation

Welcome! This is the documentation for UVVisPy, a Python package for processing and analysis of UV-visible (UVVis) spectra based on the ASpecD framework. For general information see its Homepage. Due to the inheritance from the ASpecD framework, all data generated with the UVVisPy package are completely reproducible and have a complete history.

What is even better: Actual data processing and analysis no longer requires programming skills, but is as simple as writing a text file summarising all the steps you want to have been performed on your dataset(s) in an organised way. Curious? Have a look at the following example:

 1default_package: uvvispy
 4  - /path/to/first/dataset
 5  - /path/to/second/dataset
 8  - kind: processing
 9    type: BaselineCorrection
10    properties:
11      parameters:
12        order: 0
13  - kind: singleplot
14    type: SinglePlotter1D
15    properties:
16      filename:
17        - first-dataset.pdf
18        - second-dataset.pdf

Interested in more real-live examples? Check out the use cases section.


A list of features:

  • fully reproducible processing and analysis of UVVis data

  • customisable plots

  • automatically generated reports

  • recipe-driven data analysis

And to make it even more convenient for users and future-proof:

  • Open source project written in Python (>= 3.5)

  • Developed fully test-driven

  • Extensive user and API documentation


UVVisPy is currently under active development and still considered in Beta development state. Therefore, expect frequent changes in features and public APIs that may break your own code. Nevertheless, feedback as well as feature requests are highly welcome.

How to cite

UVVisPy is free software. However, if you use UVVisPy for your own research, please cite it appropriately:

To make things easier, UVVisPy has a DOI provided by Zenodo, and you may click on the badge below to directly access the record associated with it. Note that this DOI refers to the package as such and always forwards to the most current version.

Where to start

Users new to the UVVisPy package should probably start at the beginning, those familiar with its underlying concepts may jump straight to the section explaining frequent use cases.

The API documentation is the definite source of information for developers, besides having a look at the source code.


To install the UVVisPy package on your computer (sensibly within a Python virtual environment), open a terminal (activate your virtual environment), and type in the following:

pip install uvvispy

Have a look at the more detailed installation instructions as well.
