Welcome to iFoldRNA Ver 2.0 - a web portal for interactive RNA folding simulations. We perform discrete molecular dynamics simulations of RNA using coarse-grained structural models (three-beads/residue).

Important note: Please visit the Help Center before submitting your RNA foldig jobs. Especially, please read the section of "Choosing iFoldRNA simulation-time" for the appropraite simulation time.
