CABS-fold uses an efficient simulation procedure for protein structure prediction: in de novo fashion (from amino acid sequence only), guided by user-provided template(s) (consensus modeling) and/or user-provided distance restraints (e.g. from sparse experimental data). The web server output is a coarse grained trajectory of generated conformations, its Jmol representation and predicted models in all-atom resolution (together with accompanying analysis). Typically, the output is generated within 2-12 hours.
