The annotation of sequences is performed according to the "best" PSI-BLAST score, i.e. for each sequence from the test set we select the annotated sequence from the training set that has maximum PSI-BLAST score (i.e., highest similarity). After this we assign all FunCat categories of the training set sequence to the sequence from the test set. The confidence value is 1/SCORE, where SCORE is the "best" PSI-BLAST score.

Thus this annotation corresponds to the use of k-nearest neighbor classifier with K=1.
