Tutorial

1 Choose organism: (alphabetic list) Write 3 letters or more and select it.
2 Paste one or several query DNA sequences in FASTA format (up to 20,000 nucleotides in total):
Or upload FASTA file (DNA): 
3 Select nuclease settings:
Or set your own parameters:
PAM sequence: Use predefined settings for Cas9 or Cpf1, or set custom parameters for other nucleases. If necessary, write a different PAM sequence (in IUPAC notation). For Cas9, positional weights based on Hsu et al. (2013) are used by default. See tutorial pages for details on off-targets score's calculation.
PAM position: 5' 3'
