The DiNAMO software implements an exhaustive algorithm to detect over-represented IUPAC motifs in a set of DNA sequences. It has two modes: scanning mode (default), where all windows are parsed, or fixed-position mode (see optional parameter -p ), where only motifs occurring at a specific position in the sequences are taken into account.
DiNAMO can be used in a variety of applications, such as ChIP-seq peak analysis for transcription factor binding sites identification, or finding motifs that induce systematic sequencing errors.
Binaries for Windows, OS X and Linux are available here.

DiNAMO takes as input two fasta files, which contain respectively the positive dataset (signal.fa) and the negative dataset (control.fa). You should specify also the motif length '-l'. Optionally, you can provide a maximum number of degenerate letters '-d'. The output file contains the over-represented motifs found in the positive dataset compared to the negative dataset, in the MEME format (see http://meme-suite.org/doc/meme-format.html).
