This webservice allows the user to

- upload a textfile that contains RNA sequences together with the corresponding secondary structures (encoded in bar bracket notation, an example can be found here);
- this data is used to train a stochastic context-free grammar according to the Maximum Likelihood principle and
- to determine averages of length dependent contributions to the free energy (e.g. contributions of hairpin loops) according to Turner's model.

Since the computations to be performed are rather time-consuming they are submitted to a queue; the output will eventually be provided for download. If you make use of this service for your own research, please cite the following paper.
