hifiasm-meta exit!

[Giotto187]

For assembly of metagenomic samples with HiFi reads, I ran hifiasm-meta with default parameters. The command line was as follow:
hifiasm_meta -t 32 -o asm hifi_reads.fastq.gz

But the process was exit in the step of "checkpoint: post-assembly". The log file showed:

Perplexity too large for the number of data points!

How can I fix it? I'm looking for your reply. Thank you very much!

Sorry for the delay. And sorry, the log is confusing, will fix soon. The assembly has finished. It has produced a contig graph with too few contigs, and the post-assembly genome binning stopped at clustering step.

The output: the assembly is asm.p_ctg.gfa, and the post-assembly binning is asm.rescue.fa (might be empty).
