This could be interesting. NIST & COSMOS ID and ABRF are conducting a metagenomic sequencing methods challenge.
From their site:
When using metagenomic methods to assess the content of a complex microbial sample, there are many steps in the measurement process where bias might be introduced; including, but not limited to: sample collection and storage, DNA extraction method, library construction and/or PCR, NGS platform, raw data filtering and data analysis/interpretation.
Investigating and understanding the source and extent of measurement bias is often accomplished through the development and utilization of a shared reference material (“ground truth”) followed by repeated measurements of the material in multiple independent laboratories.
Welcome to The NIST-ABRF-CosmosID Metagenomic MVP Challenge v1.0
We have a metagenomic reference material (“ground truth”) and you are the independent laboratories! This challenge is open to the community at-large, but we are limiting the number of participants to the first 80 who sign-up.
This Challenge (v1.0) is intended to be the first of many challenges that will each address a different step of the measurement process. The goal of Challenge v1.0 is to specifically identify and understand measurement bias associated with 1) shotgun library preparation techniques and 2) next-generation sequencing platforms. We recognize that this only addresses a small aspect of the larger measurement process. This is intentional and it is our intent to address other steps of the measurement process in future challenges.
