Bioinformatics concepts and best practise should be more thoroughly addressed

Comments from @cmeesters on this topic:

• fastx is totally outdated, tools like cutadept are meanwhile good replacements. It is ok to use fastx for didactics, though, as participants can view all steps for quality processing in detail. A note on the state-of-art should be given regardless.

• the assembly part comes out of the blue and is unrelated to everything before. If you want it, you need additional material, describing the background. Best put it into a separate chapter (or several), then.

• genome assembly is an intricate challenge, recommending a relatively outdated tool like velvet is dangerous, as there are numerous follow-up implementation tailored for various genome types.
