Challenges in data analyses and data storage for metabarcoding

The working group of the DNAquanet COST Action dealing with data analyses and storage for use metabarcoding approaches in biodiversity assessment, namely Working Group 4, had two main goals. On one hand comparison available analytical pipelines, while keeping track new advances bioinformatics, on other to deal potential issues sharing era big data. Such activities were carried out through discussions at meetings Action, organisations workshops, online surveys, meta-analyses.The achievements first line activity, comparing will be summarised talks session, differences clustering algorithms obtain clusters sequences that are then used subsequent inference. session introduce different pipelines currently developed improve way biological monitoring can performed.The achievement second sharing, flash talk current scenario pitfalls related raw from massive sequencing.The provide examples applications analyse using DNA sequence data.We confident pluralism presented supporting interactions a convergence towards optimisation best metabarcoding.
