I am currently working on some de novo genome assembly with pacBio data. I used Canu for assembly but I didn't have access to quiver (or arrow) for data polishing. What can I do now? I can't find any tools for replace quiver, so I'm a little bit stuck...

Thanks !

It is an old thread, but as there are no answers on which polishers to use, I will add my experience.

I have tested wtdbg2 polishing module and Racon. Both provided good improvements over either a miniasm or wtdbg2 assemblies - I would imagine they would work fine for a Canu assembly as well. I also performed a Flye assembly, which has a built-in polishing step, and for my data, Flye resulted in the best assembly as per BUSCO evaluation.

A new polisher called ntedit https://github.com/bcgsc/ntEdit is another alternative to RACON and wtdbg2 polishing.

Well, I use Canu alone, and it don't contain a polisher. I wll try to use the pacBio polisher.
