XSauci

• Public-domain program for visual comparison of genetic sequences
• Based on Correlation Images
  • each row of image corresponds to a distinct alignment of 2 sequences
  • each pixel colored based on similarity metric applied to overlapping sequence elements
• sequence relationships appear as readily perceived patterns of lines
• Dynamic filtering for removing short spurious sequences of matches
• Database operations
• Feature-preserving compression
• User-specified gap filling
• Graphical presentation of density and distribution of sequence elements
• Applied to other domains (text, shapes)
