Welcome to the stochastic Web Server

The stochastic server takes a sequence file of nucleic acids, either DNA or RNA, and generates a representative ensemble of secondary structures, generated by statistical sampling from the folding space. Note that this calculation may take a long time, particularly if the ensemble size is large.
