Pyknotid
========

Python (and optional Cython) modules for detecting and measuring
knotting and linking. pyknotid can analyse space-curves, i.e. sets of
points in three-dimensions, or can parse standard topological
representations of knot diagrams.

A graphical interface to some of these tools is available online at
`Knot ID <http://inclem.net/knotidentifier>`__.

pyknotid was developed as part of the Leverhulme Trust Research
Programme Grant RP2013-K-009: Scientific Properties of Complex Knots
(SPOCK), a collaboration between the University of Bristol and Durham
University in the UK. For more information, see the `SPOCK homepage
<http://www.maths.dur.ac.uk/spock/index.html/>`__.

If you use pyknotid in your research, please `cite us
<http://pyknotid.readthedocs.io/en/latest/sources/about.html#cite-us>`__.

Questions or comments are welcome, please email alexander.taylor@bristol.ac.uk.
