I did some de novo genome assemblies with Illumina PE data using SPAdes, whereas most of them consisting of a large number of contigs(>1000). I have several questions below.

  1. Do we need to filter short contigs?
  2. How to determine the appropriate length threshold？

  • $\begingroup$ Hi, YP CHEN, could I know what kind of genome it is? bacterial? viral? eukaryotic? How long is the genome? $\endgroup$

  • $\begingroup$ Fungal genomes， genome sizes are about ~ 50M $\endgroup$

  • $\begingroup$ Thanks. I can't help in that case. But I guess what determines your length threshold is what use you intend to make from that assembly. $\endgroup$
