 What is the minimum coverage required to run Canu?

+    For eukaryotic genomes, coverage more than 20X is enough to outperform current hybrid methods. Below that, you will likely not assemble the full genome.
 
 
 My genome is AT (or GC) rich, do I need to adjust parameters?  What about highly repetitive genomes?
