摘要
In some embodiments, the disclosure relates generally to methods, as well as related systems, compositions, kits, apparatuses and computer-readable media, comprising a multiplex molecular tagging procedure that employs a plurality of tags that are appended to a plurality of polynucleotides. The tags have characteristics, including a sequence, length and/or detectable moiety, or any other characteristic, that uniquely identifies the polynucleotide molecule to which it is appended, and permits tracking individual tagged molecules in a mixture of tagged molecules. For example, the unique tag comprising different random tag sequences alternating with fixed tag sequences, can uniquely identify an individual polynucleotide to which it is appended, and distinguish the individual polynucleotide from other tagged polynucleotides in a mixture. In some embodiments, the multiplex molecular tagging procedure can be used for generating error-corrected sequencing data and for detecting a target polynucleotide which is present at low abundance in a nucleic acid sample.
