@isaacovercast Hi Isaac -- just checking in to see if you've had any luck with the error that @jhoepke @caesantibanez @sandrahoffberg @Jamie_Bio_twitter @twpierson and some others were running into with empty arrays at Step 7. If you have a suggested workaround, even if it's not a full fix, I'd be very grateful! I'll also be interested if you solve the discrepancy between denovo and reference+denovo assemblies. Thanks again.

@tim-oconnor @Jamie_Bio_twitter Yeah, sorry I'm behind on things a bit. This is still on my stack, will try to get to it this week.
