DiNAMO

DiNAMO detects over-represented IUPAC motifs in DNA sequences to identify approximate and degenerate motifs in large-scale datasets generated by high-throughput sequencing technologies.

Key Features:

• Exhaustive Algorithm: DiNAMO employs an exhaustive search algorithm for comprehensive motif discovery, in contrast to greedy or probabilistic methods, enabling detection of rare motifs.
• IUPAC Motif Discovery: Identifies degenerate motifs using IUPAC models and performs exact searches for complex IUPAC patterns in DNA sequences.
• Robustness to Noise: Maintains motif detection performance in noisy datasets, supporting analysis despite sequencing noise.

Scientific Applications:

• ChIP-seq Peaks Analysis: Applied to analyze ChIP-seq peaks for identification of transcription factor binding sites and other protein–DNA interactions.
• Systematic Sequencing Error Analysis: Used to examine systematic sequencing errors to help distinguish technical artifacts from true biological signals.

Methodology:

DiNAMO uses an exhaustive search algorithm and supports a scanning mode with sliding windows and a fixed position mode.
