Taxonomy: Technique Branch / Method. Workflows sit above the mechanism and technique branches rather than replacing them.

Published Workflows
Objective: Accurately characterize intra-host influenza quasi-species diversity by reducing sequencing error sufficiently to detect low-frequency variants and quantify diversity at single-particle level.
Why it works: The workflow is described as working because the single unique molecular identifier strategy reduces sequencing artifacts to a reported error rate of about 10^-5, allowing mutation frequencies above background error to be interpreted as biological signal.

Implementation Constraints

The abstract supports that the method requires unique molecular identifiers and a sequencing workflow capable of single-molecule or single-particle analysis.; requires use of unique molecular identifiers
Independent follow-up evidence is still limited. Validation breadth across biological contexts is still narrow. Independent reuse still looks limited, so the evidence base may be fragile. No canonical validation observations are stored yet, so context-specific performance remains under-specified.
