hits
a data frame generated from searchHits, which contains IsMismatch.posX
(Indicator variable indicating whether this position X is mismatch or not, 1
means yes and 0 means not, X = 1- gRNA.size) representing all positions in
the guide RNA, abbreviated as gRNA),strand (strand of the off target, + for plus and - for minus
strand), chrom (chromosome of the off target), chromStart (start position of
the off target), chromEnd (end position of the off target),name (gRNA name),
gRNAPlusPAM (gRNA sequence with PAM sequence concatenated),
OffTargetSequence (the genomic sequence of the off target), n.mismatch
(number of mismatches between the off target and the gRNA), forViewInUCSC
(string for viewing in UCSC genome browser, e.g., chr14:31665685-31665707),
score (set to 100, and will be calculated in getOfftargetScore)
