After GPS-SUMO 2.0 predictor model was well-trained, we performed an evaluation on this model. From the evaluation, three thresholds with High, Medium and Low stringency were chosen for GPS-SUMO 2.0. The performance under these three thresholds was presented as follow:
| Threshold | SUMOylation | SUMO interaction | ||||||||
| Ac | Sn | Sp | MCC | Pr | Ac | Sn | Sp | MCC | Pr | |
| High | 88.63% | 57.45% | 95.17% | 0.5749 | 71.39% | 94.64% | 90.06% | 95.17% | 0.7551 | 68.08% |
| Medium | 86.60% | 68.24% | 90.46% | 0.5585 | 60.00% | 90.88% | 98.14% | 90.05% | 0.6823 | 53.02% |
| Low | 84.33% | 75.98% | 85.01% | 0.5293 | 51.54% | 86.80% | 99.38% | 85.36% | 0.6081 | 43.72% |
