Nearest-neighbour DNA thermodynamics
Melting temperatures and duplex stability in the DAE check and Tm strip.
Published parameters (SantaLucia, PNAS 1998), reimplemented in DnaOS.
caDNAno conventions and file format
Honeycomb and square lattice geometry, crossover spacing, and caDNAno JSON import.
Conventions and format published by Douglas et al., Nucleic Acids Res. 2009.
oxDNA
Topology and configuration exports, and the rest lengths used by bead relaxation.
Formats and parameters from the published oxDNA model (Ouldridge, Doye, Louis; Šulc et al.).
