Instructions 

Draw dotplots for all-against-all comparison of a sequence set

polydot generates a dotplot for each of an all-against-all comparison of a set of sequences. The dotplots are rendered on a single diagram. The dotplot is an intuitive graphical representation of the regions of similarity between two sequences. All positions from the first input sequence are compared with all positions from the second input sequence searching for exact matches between sequence regions ("words"). The two sequences are the axes of the rectangular dotplot. Wherever there is "similarity" between a word from each sequences a dot is plotted. The wordsize is specified by the user. Optionally, information on the sequence and location of all the exact matching regions may be written to file as a feature file.
