57 **What it does**
|
|
|
58
|
|
|
59 The package includes functions to find potential guide RNAs for input target se-
|
|
|
60 quences, optionally filter guide RNAs without restriction enzyme cut site, or with-
|
|
|
61 out paired guide RNAs, genome-wide search for off-targets, score, rank, fetch flank se-
|
|
|
62 quence and indicate whether the target and off-targets are located in exon region or not. Poten-
|
|
|
63 tial guide RNAs are annotated with total score of the top5 and topN off-targets, de-
|
|
|
64 tailed topN mismatch sites, restriction enzyme cut sites, and paired guide RNAs.
|
|
|
65
|
|
|
66 **Description**
|
|
|
67
|
|
|
68 Generate all possible guide RNAs (gRNAs) for two input sequences, or two sets of sequences and generate scores for potential off-targets in the other sequence.
