Abstract
Representing three-dimensional objects on a two-dimensional screen or sheet of paper can be
challenging. To address this issue in the context of oligopeptide alpha-helical secondary structure,
the helical wheel and wenxiang diagram visualizations have been developed. Although there exist
graphical interfaces and web servers that generate these visualizations, a Python implementation has
not yet been popularized. Here, we introduce the Python helixvis package, a companion to the R
helixvis package, as a programmatic implementation of alpha helix visualization. All the code
and output in this report is fully reproducible and available at https://github.com/subramv/
helixvis.
