1. A method for identifying one or more patterns in a plurality of sequences, the method comprising: reading a set of sequential data with an analysis system, wherein the sequential data comprises a plurality of sequences, each of the plurality of sequences representing an ordered sequence of tokens; generating, with the analysis system, a dotplot based on the tokens and representing matches between each sequence of the plurality sequences; and identifying, with the analysis system, one or more patterns within the sequential data based on the dotplot using a line fitting technique identifying linear relationships between the tokens.
