NEW!!! Since version 1.0.3 Topoly is available also for M1/M2 Apple Silicon Mac and Windows 64 Bit. Look at the Topoly requirements for details.
Welcome to Topoly¶
Topoly is a Python package that collects programs useful for polymer topology analysis. We wanted to make it simple in use, but powerful at the same time.
We provide twofold tutorial for our package. In the first part all functions are briefly presented with explanation of idea how do they work. The second part is topoly_tutorial package with examples of Topoly package usage.
What you can do with Topoly?¶
Find knots, links, lassos, theta-curves, handcuffs and their type.
Calculate knot/link invariants:
Polynomials: Alexander, Jones, Conway, HOMFLY, Yamada, Kauffman, BLM/Ho,
Brackets: Kauffman, APS,
Other: writhe, Gaussian linking number.
Find minimal surface of a loop.
Simplify polymer structure preserving its topology.
Generate random polygon structures: walks, loops, lassos, handcuffs.
Generate knot map (like in KnotProt).
Calculate sum (U) and product (#) of knots.
Visualize structures.
