This version of MEMECHIP is designed especially for discovering motifs
in LARGE sets of DNA sequences such as those produced by ChIP-seq
experiments. There is a 50MB upper limit. This corresponds to a maximum
of approximately 100,000 sequences of length 500bp.
A motif is a description of a common pattern in sequences,
such as a transcription factor binding site. Use this form to submit DNA
sequences to MEMECHIP and a number of other tools that aid in finding motifs
and evaluating the quality of the found motifs.
