1 Development of a pipeline for SNPs detection : Détection, Gestion et Analyse du Polymorphisme Des Génomes Végétaux 9, 10 et 11 Juin

2 I. Background and objectives of the pipeline Setting up a pipeline of SNPs detection to meet the needs of various projects.

3 II. Rated software BWA: software of Mapping, particularly suitable for alignment of Short Reads against one sequence of reference (Burrows - Wheeler Alignment tool). open source!!! SAM tools: toolkit for working on the output file of BWA. VarScan: software used to filter SNPs and indels from a BAM file, obtained from SAM tools. predict SNPs / Indels / Seq. Cns. Tablet: software used to view differents file formats (GFF3, ACE, AFG, MAQ, SOAP, SAM et BAM). GenomeView: software used to view differents file formats (BAM, GFF, FASTA et annotation file).

29 IV. Validation Process 1. Tests on public data (NCBI A. thaliana and V. vinifera). 2. Tests on data from Tomato (pair ends, 36 bps) and Poplar (pair ends, 70 bps) with comparison of EPGV and GAFL results (project PlanteReseq INRA). 3. Validation / modification of pipeline steps with the help of users. 4. Implementation and final validation of the pipeline with the ANR projects (GrapeReseq and Muscares).

30 V. Outlook Try other tools for mapping / SNPs calling (according to validation). Insert data into our databases: SNPs and Indels in GnpSNP - GnpGenome Contigs and Clusters in GnpSeq Put the pipeline on our website! BWA Parallelization on our clusters. Visualization of results in Gbrowse.

31 V. Outlook

32 V. Outlook beyond SNP detection Interoperability with the BioMart GnpIS URGI server. Extension of the system with other tools and pipelines (IBISA ). Link to Galaxy
