Off-target scores are calculated based on Hsu et al. 2013.
If you have not provided a genomic region, scores may differ from other sites (such as crispr.mit.edu).
Use these scores to rank guides relative to each other. Scores range from 0-100, with higher being better. Off-target scores above 50 are considered to be good guides. (For more detail, see crispr.mit.edu/about#score.)
