Issue fixed since Hifiasm-0.17.5 (r458) beta:

1. Fixed the bug when aligning UL reads, which affects all procedures of the UL-integration assembly. It would be better to rerun the UL assembly from the scratch (delete all bin files except ec.bin, ovlp.reverse.bin, and ovlp.source.bin).

Please note that this mode is not stable. There are several known issues to be fixed:

1. The UL + HiC + HiFi might introduce higher numbers of hamming errors.
2. Only tested with >=100kb UL reads.
3. The QV could be further improved.
