News & Events

Object Store

Galaxy now has a layer between the front end and disk files, and this layer is the Object Store. It allows Galaxy installations to make use of data living in more than simply a single filesystem of locally mounted disk - there are backends for a distributed store (many locally accessible filesystems) or Amazon S3 (in development). Configuration is trivial via the Galaxy config file. See the new object_store option and those following it!


  • TopHat:

    • Wrapper accepts versions 1.3.1-1.4.0, with at least 1.3.3 recommended. 1.4.0 is preferred.
    • Galaxy Main is now running version 1.4.0.
  • Cufflinks, CuffCompare, CuffDiff:

    • Wrapper accepts versions 1.1.0-1.3.0. 1.3.0 is preferred.
    • Galaxy Main is now running version 1.3.0 for all Cuff* tools.
  • SAMTools mpileup:

    • Wrapper for use in local instances.
    • Not available on Galaxy Main at this time.
  • GenomeSpace import from file browser tool updated to use their newer API.
  • EBI ENA SRA tool contributed by Iain Cleland.
  • Picard Interval List to BED6 converter added.
  • UCSC VCF external display application added.

Galaxy Track Browser (Trackster)

Fig. 1 shows a Visualization of a "rainbow" composite track generated via a "drag-and-drop" method within the Trackster UI itself. The top three individual conservation tracks are combined into a fourth single composite track underneath.


  • SAM merge functionality for job splitting.
  • Default static wrapping now works with favicon.ico and robots.txt (and other static files that may need to be mapped to in the future).
  • Provide default for robots.txt being pulled from config.
  • The email workflow action now happens even on job failure.


  • User interface (UI): A history item's details page (linked from the "View Details" icon) now contains links to the STDOUT and STDERR captured when running a tool's job command line.
  • Job Management: A new setting in the Galaxy config file, cleanup_job can take one of three values, always (the default), never, or onsuccess. This controls when temporary data, such as a job's working directory, external metadata files, and DRM output/error files are cleaned up.
  • JQuery updated to 1.7.1
  • Updated all tools which were manually filtering on tool_data_tables to determine paths to use built-in param.fields.path.
  • Allow method of accessing additional attributes from dynamic options work for multiple selects.
  • Merged in hanfeisun/galaxy-central-i18n (pull request #26).
  • Enhance the datatypes registry to:

    • (a) enable use of config files that do not include a "sniffers" tag set section
    • (b) not load a datatype if the registry already includes a datatype with that extension
  • Enhance the datatypes registry so that it can be persisted as an xml file, which is then used for all tools instead of the datatypes config file.
  • Eliminate all references and support for datatype indexers since they have never been used - datatype converters do the same thing.
  • Security: sanitize output anytime a raw text/html dataset is served via dataset/display.
  • Security: sanitizer also now removes javascript content from sanitized anchors, and correctly prevents a whitespace loophole.
  • ObjectStore: Variable multiple outputs (collect_primary_datasets) and components that use collect_child_datasets tuned for new process.

Bug Fixes

* Support display of extra files/composite types in published items. Fixes []( * Standardize code and error messages on 'public name' rather than 'username' * When exporting a history archive, use user dataset names rather than Galaxy dataset names. Fixes []( * Update EMBOSS tools to use quotes to escape user specified parameters during commandline substitution. Fixes []( * Escape backslashes and quotes in name attributes for UCSC external display applications which use bigDataUrls. Remove no longer required strip_https attribute. Fixes []( * UCSC BAM display will now pass the pairEndsByName attribute. Fixes []( * Allow tools with zero inputs. Fixes []( * Allow not specifying a value attribute for an optional tool parameter. Partially fixes []( * Add __non_zero__ method to ToolParameterValueWrappers. Allows boolean checks directly on wrapped parameter values. Fixes []( * Display application configuration not supported in Automatic Installation. Fixes []( * Data types configuration not supported in Automatic Installation. Fixes []( * Fix for browsing libraries in IE. Previously json2 wasn't being loaded, which is needed in IE for jstorage to work.
