The ChIPHorde extension can be used to discover multiple significant motifs in a given dataset using two independent filtering strategies.

Input sequences – Collection containing input reads.
Start length – Start length of the matrix
Stop length – Stop length of the matrix (less or equal than start length)
Motifs count limit – Maximum number of motifs to discover
Filtering mode – Whether to mask polyN ("Mask") or to drop entire sequence ("Filter")
Number of threads (expert) – Number of concurrent threads when processing
Step limit (expert) – Step limit
Try limit (expert) – Try limit
GC percent (expert) – Fraction of GC nucleotides (0..1)
ZOOPS factor (expert) – Zero-or-one-occurence-per-sequence factor
Use peak profiles (expert) – Whether to use peak profiles (if available)
Output matrix library – Path to the matrix library to put matrix into (will be created if not specified)
Matrix name prefix – Prefix for the matrix name. It will be followed by number.
