+ RNAalifold is part of the Vienna
+ RNA Secondary Structure Prediction and Comparison Package. It was
+ described in 2008 by Ivo L. Hofacker, Sebastian Will, Andreas R.
+ Gruber, and Peter F. Stadler, RNAalifold: Improved consensus
+ structure prediction for RNA alignments. (BMC
+ Bioinformatics, 9:474, 2008).
+
+ Example RNAalifold Output
+ RNAalifold prints a consensus alignment and mfe structure to stdout with its
+ associated energy. Depending on the arguments given, other information such as
+ alternate structures are displayed below while base pairing probabilities (-p or --MEA
+ options) are stored in a separate 'alifold.out' file.

+ Running RNAalifold from Jalview
+ To run RNAalifold go to Webservices→RNA Structure Prediction
+ and choose RNAalifold Defaults to run with no arguments or
+ edit settings and run ... to adjust the parameters before running.
+ Details of all the RNAalifold parameters can be found in the
+ RNAalifold Manpage.
+ JABAWS and Jalview support a selection of the RNAalifold arguments only.
+
Supported Arguments which give alternate structures
+
+ Partition Function (-p)
+ Calculate the Partition Function and base pairing probability matrix in addition to the mfe
+ structure. A coarse representation of the pair probabilities in the from of a psuedo
+ bracket notation, as well as the centroid structure derived from the pair probabilities
+ are displayed. The most likely base pairings are stored in a separate file by RNAalifold
+ and represented in Jalview by a bar graph annotation line labelled 'Contact Probabilities'.
+
+ Maximum Expected Accuracy Structure (--MEA)
+ Calculate an MEA structure where the expected Accuracy is computed from the base pair
+ probabilities. A more detailed description is found in the
+ RNAfold documentation.
