RNAStructML is a format for storing rna secondary structure information. One widely accepted usage for rnatools, such as RNAshapes {http://bibiserv.techfak.uni-bielefeld.de/rnashapes}, RNAfold {http://www.tbi.univie.ac.at/~ivo/RNA/} and Mfold {http://www.bioinfo.rpi.edu/applications/mfold/old/rna/form1.cgi} is the proprosal of rna secondary structures, based on thermodynamic principles. RNAStructML is based on SequenceML and uses DotBracket strings for storing the structure information. Synonyms for this element
