ZeroDivisionError: float division by zero in estimate_unique_local.py

[Wwwwwwwyc]

hello!
Thanks for the powerful verkko tool, but I had some minor issues while using it.

I run:

verkko -d test --hifi hifi.fq.gz --nano ultralong.fq.gz

and get the stop in 4-processONT. processONT.err is:

Step 1a
10000

Step 2a
inserted 0 gaps
inserted 0 gaps
inserted 77 gaps

Step 2b

Step 2c

Step 2d

Step 3a

Step 3b

Solid ont coverage 34 and hifi 18
first unique coverage estimate: 10.152409747278957
Traceback (most recent call last):
  File "/home/verkko/lib/verkko/scripts/estimate_unique_local.py", line 151, in <module>
    global_average_coverage = float(coverage_sum) / float(coverage_count)
ZeroDivisionError: float division by zero

Hi, could you please share the output folder 4-processONT? Here are the instructions for sharing data: https://canu.readthedocs.io/en/latest/faq.html#how-can-i-send-data-to-you

Thanks for your help. We should have uploaded the folder, could it be seen?

No, I don't see any recent uploads in the folder. You should be able to upload a tar of the folder.

Usually, this error happens when you have no long nodes in your assembly (over 100kb). How much input HiFi coverage did this assembly have?

Idle, can't reproduce locally without shared data. Re-open if you're able to share the data.
