Presentation

The need for genomic data analysis continues to grow. To best help our collaborators in the analysis of their data, we have been offering since 2016 a range of services designed to meet their needs in term of training, support and collaboration for large-scale projects. Migale has a recognized expertise in data analysis and application/workflow development in bioinformatics, multi-omics analysis ((meta)genomics, (meta)transcriptomics) for microorganisms.

For now, 7 people of the Migale team dedicate time to this service:

  • Olivier Rué is a bioinformatician engineer. He is in charge of the data analysis service on the Migale bioinformatics facility. He specializes in the analysis of metabarcoding and metagenomics data.
  • Christelle Hennequet-Antier is a research engineer in statistics. She specializes in multi-omics data analysis using statistical approaches.
  • Cédric Midoux is a bioinformatician engineer. He specializes in the analysis of metagenomics data, workflow development and development of visualization interfaces.
  • Mahendra Mariadassou is a Ph.D. in statistics. He is involved in the development of new statistical methods and tools for metabarcoding analysis.
  • Mouhamadou Ba is a Research Engineer. He is in charge of the text and data mining analysis on the Migale bioinformatics facility.
  • Valentin Loux is the operational manager of the platform. He specializes in the assembly and comparison of bacterial genomes and metagenomics data analysis.
  • Hélène Chiapello is a Ph.D. in bioinformatics. She specializes in the assembly and comparison of bacterial genomes.

Conditions

This service is open to each scientist who needs helps in analyzing his or her data in accordance with our themes/scope (INRAE, academic or private). You will have access to all the resources made available by the platform (https://documents.migale.inrae.fr/posts/tutorials/migale-infra/).

  • The service is free of charge for academics. For members of the private sector, an offer will be made to you.
  • Opening an account on the platform entitles you to 400 GB of space (save + work). If you need more disk space, a dedicated space on the server will be opened and invoiced (at the rate of 300€ / To / year)

Quality approach

The Data Analysis service is one of the process governed by the quality approach and under our quality certification. Consequently, some procedures have been set up to provide the best possible services. This procedure allows each party to know exactly what it has to do and what the other one has to do.

FAIR principles and data management

We can accompany you in the implementation of the FAIR principles by:

Data management during the project

During the project, we are responsible for the data you provide us. Raw data are deposited on two distinct servers. During the analyses, you have access to intermediate results and to the companion analyses website.

At the end of the project, the expected deliverables are sent to you and we are no more responsible of your data. You can host them if you want in your own space. - helping to deposit your data on a dedicated infrastructure - reporting all commands (tools, versions) for reproducibility (in the companion website)

Scope of the data analysis service

Metabarcoding

We have extensive experience in metabarcoding data analysis (16S, ITS, RPB2, D1D2, gyrB…). According to your needs, we choose the most appropriate tool.

We develop and provide shiny interfaces to explore and manipulate metabarcoding data:

  • easy16S is a user-friendly web application enabling you to easily explore, visualize and analyze amplicon sequencing metagenomics data.
  • affiliationExplorer is a user-friendly graphical interface to choose between different conflicting affiliations that the FROGS pipeline produces.

Metagenomics / Metatranscriptomics

We have extensive experience in metagenomcis data analysis. From quality control to functional annotation, we have workflows to clean, assemble, predict and annotate genes from Illumina metagenomics data. Recently, we have implemented workflows for dealing with long-reads data.

Genome assembly, annotation and comparison

We have extensive experience in phage, archaeal and bacterial genome assembly, annotation and comparison of multiple assemblies.

Text-mining

We have experience in literature data analysis (textual data analysis). We have tools to cover the following analysis around microbiology from sources like PubMed:

  • creation of thematic corpora (e.g., collecting a set of articles related to habitats of microorganisms from PubMed)
  • classification of textual articles (e.g., selecting pertinent articles from a corpus)
  • extraction of biological entities mentioned in articles (e.g., identifying mentions of genes in articles)

Procedures

We propose two different ways to collaborate: Collaboration and Counseling.

Collaboration

In Collaboration mode, we handle the analysis of the data.

Warning

If possible, we would like to be involved very early in the project design to give advice concerning the experimental design, the sequencing strategy, the number of samples/replicates, the randomization, etc.

We take care of storing sequencing data on our infrastructure and we provide a web report that tracks all performed analyses to facilitate reproducibility.

Support

This mode is quite different. Our role is to help you to analyze and interpret the results you obtain. We give assistance for debugging, choosing tools and parameters but don’t perform the analyses. With this service, you have access to an interlocutor available to answer your questions, supervise your treatments and help you in the analysis and interpretation of your results. It helps you to become progressively autonomous and confident in your bioinformatics skills.

"Nous aurions de notre coté a ameliorer la base de terme MESH pour limiter les faux positifs ou pouvoir obtenir des résultats plus precis : par exemple , nous n'avons pas toutes les especes car pour une meme espece plusieurs termes sont possibles ou sont notés au pluriel. Par ailleurs, Il serait interessant, par exemple dans un volet 3, de mettre les résultats de datamining sous forme graphique a l'aide d'un outils comme cytoscape afin de selectionner que quelques colonnes de resultats. Mouhamadou a pu adapter les données pour pouvoir les integrer dans le logiciel Gargantext developpé par l'Institut des Sciences Complexes et avoir une forme Graphique mais la representation  est differente (et complementaire) de ce qui peut etre defini avec les données d'origine."
