Short, practical explainers on sequencing concepts — each paired with a calculator you can try straight away.
- How much sequencing coverage do I need? What coverage (read depth) means, typical targets for WGS, WES and RNA-seq, and how to plan reads for a run.
- What is Q30? Phred quality scores explained How the Phred scale turns base-call error probability into a Q score, what Q20/Q30/Q40 mean, and why %≥Q30 matters.
