The output conforms to the
GFF format. For each input sequence the server outputs a prediction score and annotation for every residue. The positions of the linear B-cell epitopes are predicted to be located at the residues with the highest scores. The annotation, given in the column denoted "?", is determined by the given threshold for the scores. A residue annotated with an "E" is predicted as being part of a linear B-cell epitope (score above threshold), where an "." represents a residue predicted not to be part of an epitope (score below threshold).
The table below shows the relationship between selected thresholds and the sensitivity/specificity of the prediction method, calculated on basis of the epitope/non-epitope predictions. The table is based on a large benchmark calculation containing close to 85 B cell epitopes.
