Box and whisker plots of length, %GC, and G/C ratio. Box and whisker plots displaying medians, quartiles and range of the sequence length, %GC, and G/C ratio for all our test data sets. The lines of the box are at the lower quartile, median, and upper quartile values. The box width is proportional to the number of sequences in the data set. The whisker lines extend from each end of the box to the most extreme data value or have a maximal length of 1.5 times the box height. Data points beyond the ends of the whiskers are marked by +.
