Performance for the prediction of the ω-site

Predictor	BigPI	DGPI	GPI-SOM	PredGPI (cv*)	PredGPI (non cv**)
Correctly predicted proteins	23	16	15	21	24
Proteins wrongly predicted by one position	1	4	2	3	2
Proteins wrongly predicted by more than one position	1	5	7	2	0
Proteins predicted as non GPI-anchored	1	1	2	0	0

The test set comprises 26 sequences with experimentally annotated ω-site (GPIω-Set). The number of sequences is listed.

*cv = results obtained with a 20-fold cross validation prediction;

**non cv = results obtained with a predictor trained on all the 26 sequences.
