6th edition of the Workshop 

"Recent Computational Advances in Metagenomics (RCAM'19)"

September 30 - October 1, 2019

Amphi Duclaux, Institut Pasteur, Paris, France 

[Note: your ID will be asked to enter the campus; please arrive 15 minutes in avance]

This workshop aims at promoting discussions and collaborations between biologists (modelers),  computer scientists and applied-mathematicians involved in metagenomics and/or metatranscriptomics studies, either in the bioinformatics or statistical aspects of such analysis.
Metagenomics  studies  refer   to  analyses  based  on high-throughput sequencing  of environmental samples  and microbial ecosystems. Both marker-gene (16S, 18S, ITS,  ...)  and whole-genome strategies will be adressed to  cover a wide  array of question ranging  from quantifying the  microbial  diversity in  order  to  find  structuring factors to assessing the functional role of microbial communities.
The workshop will provide  an overview of the state-of-the-art methods currently used in metaomics including comparative metagenomics and metatranscriptomics.  At the  other end  of the  spectrum, case-studies with a strong methodological component will illustrate how and when these methods are useful and how they produce new biological knowledge. This includes studies that investigate the shortcomings of mature or novel methods (e.g. for clustering, inference of co-occurrence networks, detection of certain types of interaction between taxa, etc) in real life settings. 

The program of this workshop will consist mainly of presentations of refereed papers (30 minutes) and  invited talks (50 minutes). A session for PhD students/postdoctoral fellows will be also organized. Contributions are welcomed on all aspects  about bioinformatics and statistical analyses of metaomics datasets, including, but not limited to:

  • new methods, tools or pipelines involved in the characterisation of microbial diversity,
  • original methods for taxonomical assignment,
  • Metagenomics/metatranscriptomics assembly,
  • data reduction,
  • comparative metaomics,
  • models for community assembly,
  • inference of co-occurrence/abundance patterns,
  • challenges for tackling the complexity of metaomics datasets.

Note that this workshop focuses mainly on methodological aspects of metagenomics and is not dedicated to result presentations of bioanalysis studies.
