Structural DAS /02/26 3D-EM DAS Features / Annotations Genomic DAS Sequences (reference) New Fitting Results (Alignment) New EMDB annotations New 3D-EM volume maps (reference) Structures (reference) Alignment server PeppeR 3D-EM DAS Client New 3D-EM DAS: System architecture

Commands:  Returns known entries from EMDB database ( Release date are reported also, as some entries might stay unreleased /02/26 EMD1001 EMD1003 EMD1004 EMD1005 EMD1006 EMD1007 EMD1008 EMD1009 EMD1010 EMD1011 EMD1012 EMD1013 … EMD1212 EMD1213 Reference server: 3DEM EMD1001 EMD1003 EMD1004 EMD1005 EMD1006 EMD1007 EMD1008 EMD1009 EMD1010 EMD1011 EMD1012 EMD1013 … EMD1212 EMD1213

Commands:  New command: Returns the volume map (a link, actually) for the entry. Equivalent to dna or sequence queries in other DAS systems.  New xml document definition: Equivalent to DASSEQUENCE /02/26 Reference server: 3DEM ftp://ftp.ebi.ac.uk/pub/databases/emdb/structures/EMD-1017/map/emd_1017.map.gz NOTE: The LINK element points to the location where a 3D-EM DAS client should retrive the data for the volume map (ussully through ftp) ftp://ftp.ebi.ac.uk/pub/databases/emdb/structures/EMD-1017/map/emd_1017.map.gz NOTE: The LINK element points to the location where a 3D-EM DAS client should retrive the data for the volume map (ussully through ftp)

An alignment server…  Returns the list of known fitting experiments. Currently this list is manually “curated” and updated from different sources, mainly EMDB.  Where ID can be a fitting, a EMDB or PDB identifier. …plus an annotation server:  Returns used annotation types/categories.  Reports annotations about the fitting experiment conditions:  Method and software used.  Experimentalist notes.  etc /02/26 Alignment server: 3DEM_Fitting

Commands:  /02/26 Alignment server: 3DEM_Fitting … …

Commands:  Annotation reefers to the whole volume, so some fields are useless:  start / end.  orientation / phase.  subparts / superparts /02/26 Features server: 3DEM_EMDB Description Sample: "DnaB.DnaC complex from Escherichia coli "; Author: "M.Barcena,T.Ruiz,L.E.Donate,S.E.Brown,N.E.Dixon,M.Radermacher,J.M.Carazo" Retrive EMD1017 from EMDB Description Sample: "DnaB.DnaC complex from Escherichia coli "; Author: "M.Barcena,T.Ruiz,L.E.Donate,S.E.Brown,N.E.Dixon,M.Radermacher,J.M.Carazo" Retrive EMD1017 from EMDB

/02/26 A new client: PeppeR Java implementation - Architecture independent Windows Unix / Linux Mac Os Starts as a stand-alone application or Embedded in a web browser, as an applet. - Java Web Start deployment Launched directly from a web link. Easy version control and upgrade. Uses AstexViewer to display maps + pdb structures together. Features (annotations) panels from SPICE library.

/02/26 Some screenshots A new client: PeppeR

/02/26 Visual Genomics Integrating genomics with phenotype through image techniques: Light, Confocal and Electron Microscopy Tomography Visual Proteomics Mapping spatial information to locate macromolecular “nanomachines” inside simple model organisms. What about future ?

/02/26 NOW: Large data sets transfer : attachments? Avoid indirect access, through ftp SOON: New types of annotations Ontology elements Phenotypic results Quantitative, continuous values Integration between different types of reference data Allowing more cross-references between different data sources. What we’ll need ?
