crabWURCS 0.3

crabWURCS converts glycan notations, works with molecular structures, extracts glycans from coordinate files, and produces SNFG graphics. The same pure-Rust engine powers its Rust library, Python package, and command-line application.

pip install crabwurcs

import crabwurcs

glycan = crabwurcs.Glycan.parse("Gal(b1-4)GlcNAc")
print(glycan.to("wurcs"))

The 0.3 release supports CPython 3.9+, Rust 1.97+, all 87 registry symbols, and molecular/PDB interoperability for all 74 concrete registry residues.
