Remove unwanted sequence motifs while minimizing predicted changes in regulatory activity.
Legacy models are included for reproducibility.
Enter up to 10 DNA motifs separated by commas or spaces. IUPAC ambiguity codes are supported (A, C, G, T, R, Y, S, W, K, M, B, D, H, V, N). Motifs are checked on both strands.
Highly repetitive motif sets are rejected if they create more than 100 initial motif occurrences or an excessive candidate search space.
Paste one or more sequences in FASTA format, or a single DNA sequence without a header. Up to 50 sequences are accepted; each sequence must be at least 170 bp. You can alternatively upload a FASTA file below.
