I have been running hifiasm successfully for some time. However, yesterday I got a very strange result for two birds (another bird species assembled just fine). Here is the example for one of the species:
What is going on here? So my first idea of course would be that the input data is wrong. However, the normal stats for this sequence data (hifi data from a sequell machine) seem completely fine and not different from more successful assemblies.
I do get very strange genomescope results back though. With a very high read error rate:
GenomeScope version 2.0
input file = /ptmp/luelze/analysis/bPacVit/hifi/qc/reads/jellyfish/bPacVit_reads.histo

But then the Q30 from the seqkit stats seems alright? So what is happing? Does anyone have an idea?

Based on the information you provided, the reads used for assembly appear to be merely a collection of reads along with their duplicates. You may need to carefully review your data.
