By Laura Elnitski, Helen Piontkivska, Lonnie R. Welch

Mapping the genomic landscapes is likely one of the most enjoyable frontiers of technology. we have now the chance to opposite engineer the blueprints and the regulate platforms of dwelling organisms. Computational instruments are key enablers within the decoding approach. This ebook offers an in-depth presentation of a few of the real computational biology methods to genomic series research. the 1st element of the publication discusses equipment for locating styles in DNA and RNA. this can be via the second one part that displays on tools in a variety of methods, together with functionality, utilization and paradigms.

Sample text

If the input file contains results for more than one word length, then as many tables as the considered word lengths will be produced. However, if only a subset of word lengths (between min and max) is of interest, the -i and -a options can be used (-l is enough for a unique word length). The significance associated with a given score is obtained thanks to the standard Gaussian distribution with mean 0 and variance 1. 00135). Therefore, motifs with such scores are removed by default from the tables.

Getting exceptional skew scores When analyzing a DNA sequence, one can be interested to know if an oligonucleotide has a significant skew.
