Splice site sequence logos and efficiency of splice site prediction. a) Sequence logos of Physcomitrella donor and acceptor sites. b) Prediction performance of Netplantgene and svmsplice for Physcomitrella splice sites. TP = true positive, FN = false negative, FP = false positive, measured on the lefthand (%) axis. Recall (sensitivity) = tp/(tp+fn), precision = tp/(tp+fp), measured on the righthand axis.
