ISAMBARD (Intelligent System for Analysis, Model Building And Rational Design), is a Python-based framework for structural analysis and rational design of biomolecules, with a particular focus on parametric modelling of proteins.

The SOCKET program finds the Knobs-into-Holes mode of packing between alpha-helices (Crick, 1953) which is characteristic of coiled coils. It unambiguously defines the beginning and end of coiled-coil motifs in protein structures and assigns a heptad register to the sequence.


The LOGICOIL algorithm predicts the oligomeric state probabilities of a coiled-coil sequence. It curently allows to classify antiparallel dimers, parallel dimers, trimers and tetramers.
