Error message
I just started learning this software, and I don't quite understand what this error means.

[Hu Jiang]

you don't have enough memory, try parallel_jobs = 1 and pa_correction=1

[Hu Jiang]

I just realized your genome is only 700k, I'm not sure if nextdenovo is suitable for this.

[kreyszhang]

I'm so grateful, this worked.
This is a PCR product, so it is very short. And I'm not very good at this work , I don't know if there is any other assembly software suitable for short genome assembly with third-generation sequencing. I know that short genomes are not suitable for third-generation sequencing, but the time of TGS is shorter than NGS, so I still want to try it .
