Plots the average data contained in a set of WIG files (please consult http://genome.ucsc.edu/goldenPath/help/wiggle.html to know more about this format) around the first nucleotides of a annotation file.

The tool needs an transcript list, some WIG files, and a distance. For each transcript, it collects all the values around its first nucleotide, the radius being given by the distance. Then, it computes the average value for each position. A point (x, y) means that the average value in the WIG file for a nucleotide distant by x nucleotides from the first nucleotide of an input transcript is y.

You can possibly use a log scale for the y-axis.
