Located at Genoscope (CEA sequencing center for environmental genomics), the LABGeM bioinformatics team has developed MicroScope, a web-based platform for prokaryotic genome analysis and expert functional annotation.

MicroScope combines tools and graphical interfaces to analyze genomes and to perform manual curation of gene function in a comparative and metabolic context.

This platform provides data from completed and ongoing genome projects together with post-genomic experiments (i.e. transcriptomics, re-sequencing of evolved strains) allowing users to improve the understanding of gene functions. Expert annotations are continuously gathered in the MicroScope database contributing to the improvement of the quality of microbial genome annotations, and thus to the predicted metabolic networks.

MicroScope can be used as a community resource for comparative analysis and annotation of publicly available genomes but also as a private resource with restricted access rights on genomic data. In addition, we regularly hold professional trainings sessions on the use of MicroScope platform.

Formations à la plate-forme Microscope


The LABGeM team at Genoscope regularly organizes training courses dedicated to the analysis of bacterial genomes via the use of the MicroScope platform at the University of Évry.
The course "Annotation and analysis of prokaryotic genomes using the MicroScope platform" lasting 4.5 days is aimed at:

  • acquiring theoretical and practical knowledge of genome annotation tools (structural and functional annotation, metabolic networks annotation)
  • knowing how to interpret the results of functional annotation tools
  • knowing how to carry out various comparative analyzes: analyzes of conserved syntenia, pan-genomes, phylogenetic and metabolic profiles
  • learning to interpret the results of metabolic network prediction tools and search for candidate genes for enzymatic activities
  • applying those tools to the analysis of genomes of interest to the participants 

Each session is made up of half theory and half practical work. During the training, participants have the opportunity to work on their own data during practical work.
This training is aimed at doctoral students, engineers, researchers, experienced biological or medical laboratory technicians. It concerns both people who already have an annotation project on the MicroScope platform and wishing to deepen its use, as well as those wishing to learn microbial genomics.
In addition, if you are a user of the MicroScope platform and you have already followed the training "Annotation and analysis of prokaryotic genomes using the MicroScope platform" a few years ago we have implemented a new training , the "MicroScope Platform - Advanced Course" training in order to update your knowledge on the latest evolutions of the platform and to deepen some of its major functionalities.
This training, lasting 2 days, will consolidate your use of the platform but also go further:

  • Presentation of the evolutions of the MicroScope platform
  • Presentation of the new flagship features of the MicroScope platform
  • Presentation of tools for RNA-seq analyzes
  • Deepening of the functionalities allowing the exploration of the bacterial metabolism

Explanation about this distribution:

From <400 user accounts in 2006, MicroScope counts >4200 personal accounts at present time. The number of registered users has doubled since 2013, and the platform has even widened its international popularity with 64% of accounts outside France.

Many international projects are conducted through the platform involving users from distant geographic areas. Although authentication is not required to navigate in MicroScope, it allows users to annotate genes and save data on their personal session.

On average per month, we count 360 active accounts (i.e. the user logged in at least once in the month). 

Platform's own projects
  • Tools for bacterial genome annotation and comparative genomics
  • Metabolic network reconstruction
  • Curation of metabolic data
  • Discovery of new enzymatic activities
  • Quantitative transcriptomics via RNA-seq
  • Variant analysis
  • Pangenomics and (meta)genomics analyses
