A Julia wrapper of the Logomaker Python package to plot sequence logos.
import Logomaker, PythonCall
color_scheme = PythonCall.pydict(Dict('A' => "blue", 'C' => "gold", 'G' => "green", 'U' => "red", '-' => "gray"))
# weights is a matrix containing scores, e.g. conservation.
logo = Logomaker.Logo(weights, collect("ACGU-"); color_scheme)
logo.ax.set_ylim(0, log2(5))
