AS (Annotation Score) plot for all clusters of 20 or more proteins, after compression. Each dot represents a cluster and is plotted according to the sensitivity and specificity of its highest-scoring AS (as defined in the text). The curve represents the high-confidence annotation threshold which was used. Dots in the upper right represent clusters that passed the threshold and were therefore annotated with high-confidence.
