CNS or Crystallography and NMR system, is a software library for computational structural biology.{{cite journal |vauthors=Brunger AT, Adams PD, Clore GM, Gros P, Grosse-Kunstleve RW, Jiang JS, Kuszewski J, Nilges M, Pannu NS, Read RJ, Rice LM, Simonson T, Warren GL |title=Crystallography & NMR System (CNS), A new software suite for macromolecular structure determination |journal=Acta Crystallogr D |volume=54 |pages=905–921 |date=1998|issue=5 |pmid=9757107 |doi=10.1107/s0907444998003254|bibcode=1998AcCrD..54..905B }}{{cite journal |author=Brunger AT |title=Version 1.2 of the Crystallography and NMR System |journal=Nature Protocols |volume=2 |pages=2728–2733 |date=2007|issue=11 |pmid=18007608 |doi=10.1038/nprot.2007.406|url=https://zenodo.org/record/895343 }} It is an offshoot of X-PLOR and uses much of the same syntax. It is used in the fields of X-ray crystallography and NMR spectroscopy of biological macromolecules.
