The assembly of genome is less than expect

[ala98412]

Hi there,

I have a genome which is expected to have ~860Mb, this result is using genome size estimation tool and also obtain from flye.
However, I try both -k=16 and -k=17, the assembly files "wtasm.dmo.cns" are less than 700Mb in size.

In addition, BUSCO score is 65.52%.

I know my species have more than 50% of repeat sequences. Should I use a larger k value?
Or is my species not suitable for smartdenovo?

Thanks.
