Hi All,
The issue shows below:
Using provided long read assembly instead of running Racon: MMH5in0E.fastq.gz

Traceback (most recent call last):

UnicodeDecodeError: 'utf-8' codec can't decode byte 0x8b in position 1: invalid start byte

I just dont know what happened during the assembly and don't know how to fix it? Can anyone help me?

And did the progress finish? I guess it has finished but failed to output the results?
