phonechars 0.1

Extract phonological phylogenetic characters from aligned data

phonechars

phonechars is a Python library and command-line tool for extracting phonological phylogenetic characters from aligned lexical data, both for purposes of investigation into correspondence sets and phylogenetic analyses.

Installation

In any standard Python environment, phonechars can be installed with:

pip install phonechars

How to use

The library can be conveniently used by means of the phonechars command-line tool. While different options are available, a simple call to the program when provided the path to a wordlist of aligned data will generate three files with related information:

• A .chars.tsv file, extending the alignment information with correspondences inferred by means of different methods (currently, only a method modified from List (2019) and available via the lingrex library is offered)
• A .corrs.tsv file, informing the detected correspondences
• A .nex (NEXUS) file, suitable for analysis with standard phylogenetic tools including SplitsTree and BEAST2

A demo file, with information from Ryukyuian dialects as presented in Huisman (2022), is distributed with the standard installation and can be used for testing the command-line tool:

$ phonechars demo/ryukyu.tsv
