Phix genome kmer length
I am working on very small genome size 5500 bp. For de novo assembly how to pick optimal kmer for this genome size.

Assembly should take seconds, so the best option is to use all kmer lengths up to ~95% of read length and pick the best assembly. In this case, the best assembly will be any that produce a single ~5500bp contig. If you are having trouble producing a good assembly, I suggest trying Tadpole in the BBMap package, which tends to do a good job assembling viruses that for whatever reason produce strange results in other assemblers such as Spades.

Is There Any Reason To Do De Novo Transcript Assembly If A Reference Is Available?
written by Ryan Thompson
It's not clear what you are trying to accomplish, or what kind of data you have, so there's no way to give a good answer to this question. Can you please give a complete description of the situation?
I have Miseq sequencing data for phage virus, the genome size about 5kb. For de novo assembly,depending upon kmer, our contig assemblies will vary. I want to know what is ideal kmer value or range of kmer values for 5kb genome size.
