Do Not Use "PacBio SMRT" and "HiFi" Interchangeably for Long Reads
Why this matters
SMRT sequencing involves real-time observation of single-polymerase synthesis within a Zero-Mode Waveguide (ZMW). Current HiFi reads belong to the Circular Consensus Sequencing (CCS) category, which improves consensus accuracy by reading the same molecule multiple times; these must be distinguished from the length and error characteristics of past Continuous Long Read (CLR) data. Long accurate reads are valuable for resolving repeats, structural variants (SVs), phasing, genome assembly, and full-length transcript analysis. However, results depend on input molecule quality, insert size, coverage, chemistry, and software versions. Always record not only the platform name but also the instrument model, chemistry version, and analysis software version.
