Vfold model

Vfold [1-6] is a software package to evaluate the stable structures and the folding free energies for RNA secondary structures and pseudoknotted structures. Recently, the Vfold model has been extended to predict loop-stem tertiary interactions in RNA pseudoknots [6].

If you wish to access the Vfold web server and package, please visit the Vfold server main page.
