This may be caused by nextpolish not finishing running.,Could you paste its running log to here?

Thank you very much for your reply!

I first used quality-filtered ultralong ONT reads and common ONT reads to polish the assembly for three rounds, setting ‘task = best rewrite = yes rerun = 3’ in the parameter config file. The assembly polished by ONT data was then further polished for three rounds with PacBio HiFi reads,setting‘task = best rewrite = yes rerun = 3’ in the parameter config file.

It is better to use NextPolish2 to polish your genome (assembly polished by ONT data) with HiFi reads
.

Thanks for your reply and help!
The genome assembly I assembled through hifiasm using HiFi data is not very good, so I am currently using the results assembled by Nextdenovo, which is better. My data is a bit special, and there should be more errors in the results I assembled using nextdovo.
I have carefully learned about nextpolish2, which you developed. It is suitable for polishing high-quality assembly . Is nextpolish more suitable for my situation?
In addition, I hope to use my HiFi sequencing data for polishing. Because it is difficult to use HiFI data for assembly, I hope to use my hifi data in the polishing process.
Finally,why does polishing result in a significant decrease in genome size?
from nextpolish.
- nextpolish2 is suitable for your assembly, so you can have a try.
- There may be an unknown bug, but it cannot be fixed unless I can reproduce this bug.

Thank you for your reply and help!
I will try using Nextpolish2 to see if it resolves the issue.
Could it be that my HiFi data is somewhat unique, leading to some unknown issues when applying it to Nextpolish? Because I didn't encounter any significant reduction in genome size when processing with ONT data.

I'm not sure, unless I can reproduce the error.
from nextpolish.
I performed polishing through nextpolish2 and found that it still resulted in a significant reduction in the genome, by about 30M.
Do you know what causes this situation?
Very much looking forward to your reply
