motifStack

motifStack visualizes multiple sequence motifs for DNA, RNA, and protein sequences to enable comparison of motif similarity and conservation across datasets.

Key Features:

• Motif type support: Supports nucleotide (DNA/RNA) and protein (amino acid) sequence motifs.
• Multiple-motif visualization: Produces graphical representations of multiple sequence motifs for direct visual comparison.
• Similarity-aware comparison: Handles motifs with varying similarity scores to highlight conservation and variation across datasets.

Scientific Applications:

• Comparative analysis: Enables visual comparison of motif conservation and variation across species or experimental conditions.
• Functional genomics: Assists exploration and identification of regulatory elements and functional sites relevant to gene expression regulation.

Methodology:

Implemented as an R package distributed via Bioconductor.
