Variant-aware Cas-OFFinder

Variant-aware Cas-OFFinder is a variant-aware potential off-target sites identifying tool based on Cas-OFFinder. Using a reference genome alone to search potential off-target sites has many drawbacks since it may not contain individual variants, making it challenging for therapeutic applications. VarCas-OFFinder considers individual variants along with reference genomes to search potential off-target sites.
