DNA metabarcoding has broad multidisciplinary potential, as demonstrated by the expansion in use of metazoan wocDNA COI metabarcoding among users from very diverse backgrounds. The diversity of applications of metabarcoding requires the concomitant bioinformatic techniques to be flexible and adaptable, and the field remains under active development. Thus it would not be productive to attempt to prescribe pipelines, tasks or even software tools in the name of standardisation, as there is no one-size-fits-all approach in metabarcoding. However, some degree of harmonisation is required to ensure quality, reproducibility and potential integration in metastudies (Tedersoo et al., 2015). Additionally, the absence of a harmonised framework of bioinformatic processing can act as a barrier for potential new users (Liu et al., 2020), hampering the growth of the field. To these ends, we thus propose a set of recommendations that we believe all researchers in the field should consider when designing and reporting their wocDNA COI metabarcoding bioinformatics pipeline, with the hope that they will catalyse harmonised implementation.
