A visual tool for DNA repeats screening

DNA sequence analysis has been developing to reveal some hidden structure, to distinguish coding from noncoding regions in DNA sequence, and to explore structural similarity among DNA sequences. DNA repeats are associated with human disease, seems to play a role in genome organization and evolution and are important in regulatory processes. A lot of the methods for finding repeated sequences use signal processing techniques which implies distances, similarities and consensus sequences to generate candidate sequences. This paper presents results obtained using a mapping algorithm and a custom dot-plot analysis combined with image processing techniques, to isolate the position of DNA patterns with different lengths.
