Hit scores
| Parameter | Spec. Score cut-off | Colour | Comment |
| Hit to same gene | Colour | Hits to the same accession or genes with 100 percent identity (i.e. likely transcript variants). It is advisable to always check the genes hit. | |
| High scoring hit | ≥80 | Colour | Hits are very likely to cause an off-target effect |
| Medium scoring hit | <80¸≥40 | Colour | Hits with a small chance of causing an off target effect. |
| Low scoring hit | Colour | Hits very unlikely to cause an off-target effect |
The mismatches are colour coded based on the weighting of that position.
