97 **What it does**
98
99 The package includes functions to find potential guide RNAs for input target se-
100 quences, optionally filter guide RNAs without restriction enzyme cut site, or with-
101 out paired guide RNAs, genome-wide search for off-targets, score, rank, fetch flank se-
102 quence and indicate whether the target and off-targets are located in exon region or not. Poten-
103 tial guide RNAs are annotated with total score of the top5 and topN off-targets, de-
104 tailed topN mismatch sites, restriction enzyme cut sites, and paired guide RNAs.

106 **Description**
107
108 Design of target-specific gRNAs for the CRISPR-Cas9 system by automatically finding potential
109 gRNAs (paired/not paired), with/without restriction enzyme cut site(s) in a given sequence, search-
110 ing for off targets with user defined maximum number of mismatches, calculating score of each
111 off target based on mismatch positions in the off target and a penalty weight matrix, filtering off
112 targets with user-defined criteria, and annotating off targets with flank sequences, whether located
113 in exon or not. Summary report is also generated with gRNAs ranked by total topN off target
114 score, annotated with restriction enzyme cut sites and possible paired gRNAs. Detailed paired gR-
115 NAs information and restriction enzyme cut sites are stored in separate files in the output directory
116 specified by the user. In total, four tab delimited files are generated in the output directory: Off-
117 targetAnalysis.xls (off target details), Summary.xls (gRNA summary), REcutDetails.xls (restriction
118 enzyme cut sites of each gRNA), and pairedgRNAs.xls (potential paired gRNAs).
