assemble result

What is the NextDenovo version you used? and how about the genome size, heterozygous rate, and repeat content? I do not suggested use corrected data, because NextDenovo will correct the raw data and filter some low quality or unuseful seeds. BTW, Could you provide the co-line pictures?

How about the assembly result using canu?

1. I used the NextDenovo v2.1-beta.0 2. The genome size I used is about 980 Mb, heterozygous rate is 0.119% The figure 1 is raw data, figure 2 is corrected data Figure1 Figure 2

I can not see the figures, if you have problem to upload the figures to github, you can send the figures to my email: huj_at_grandomics.com. BTW, could you provide the configure file and the assembly log (the last step log)?

Hi, Dr. Hu I sent it to you few minutes ago

I find your seed_cutoff is very short? How many data you used to do the assembly?

[shehongbing]

My raw data is about 40 G.

Your data is not enough for assembly using the currently version of NextDenovo with default options, because all default options are optimize with 60-100x nanopore data. So it will produce an unexpected assembly result. But if you still want to use NextDenovo to do the assembly, you can try to use the option correction_options = -b and change -k 30 in sort_options and than rerun all pipeline, while I can not guarantee you can get a good result. You also can try to other assemblers. I will release a set of preset parameters for assembly with low-depth data in the future.

Thank you
