aaRNA is an RNA binding site predictor using various features that out-performs sequence- or structure-only predictors.
Sequence-based predictors are usually shortsighted, due their fragmented view of a binding site. By contrast, structure-based predictors can reach higher specificity but usually at a cost of sensitivity.
The aaRNA server requires sequences to be input in FASTA format. Structures can be input as PDB identifiers or as user-provided structures in PDB format.
