No haploid.gfa files output in trio-binning mode #636

Hi, I have HiFi reads, ONT-reads, HiC reads, and parents illumina short reads. So, I ran hifiasm with trio-binning mode to conduct haplotype assembly with the code 'hifiasm -o prefix.asm -t 32 --ul ont-reads.fa.gz --h1 hic-1.fa.gz --h2 hic-2.fa.gz -1 pat.yak -2 mat.yak Hifi-reads.fa.gz'. However, the output didn't have the two haploid gfa files. The outputs are as follows:

1712889273430

There's no error in log file. Could you give some advices? Thank you for your assistance.

The description provided earlier was incorrect. The log file displayed 'Segmentation fault' at the end. Is it appropriate to use these sequence data together in hifiasm trio-binning mode? Hope you will give me some advice on using these data to assembly haplotype genome. Thanks!

Sorry for the late reply @tzjingyang. Hifiasm cannot use Hi-C and trio phasing at the same time. In most cases, it would be better to use trio-binng with yak index since trio-binning is more reliable than Hi-C phasing.

Thanks. Then, where should I use the hi-c data to get exact results? or the hi-c data only used in scaffold steps.
