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!
Tools
-
- 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.
-
- 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)
- Recent publication: Jeremy Goecks, Kanwei Li, Dave Clements, Team, The Galaxy, James Taylor, The Galaxy Track Browser: Transforming the genome browser from visualization tool to analysis tool. Biological Data Visualization (BioVis), 2011 IEEE Symposium on (October 2011), pp. 39-46.
- Simplified user interface that uses icons exclusively for actions.
- Numerous performance improvements.
- SAM datasets (including very deep) can be visualized.
- All rows for feature tracks--BED, GTF, SAM, BAM--can now be displayed.
- Custom composite tracks now available: any amount of wiggle data can be combined into a single track. See Fig.1.
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.
Workflows
- 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.
Source
- User interface (UI): A history item's details page (linked from the "View Details"
icon) now contains links to the STDOUTandSTDERRcaptured when running a tool's job command line. - Job Management: A new setting in the Galaxy config file,
cleanup_jobcan take one of three values,always(the default),never, oronsuccess. 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 select_param.fields.name 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.
Tool Shed
-
New features:
- Add the ability to reset all metadata (for every change set) in a tool shed repository (currently restricted to an admin).
- Enhance User preferences within a Galaxy tool shed to enable users to elect to receive email when content is first uploaded to a new repository. Also add a new grid interface to enable users to easily manage registering with any tool shed respositories to receive email when changes are made to the selected repositories.
-
Existing tool shed fixes:
- Make the use of the 'require_login' config setting functionally correct for the tool shed, and debug it's use in the Galaxy framework as well.
- Enhance the process for displaying a workflow in a tool shed repository so that workflows in change sets other than the repository tip can be viewed.
- Do not allow public user names to be changed within the tool shed if the user has created a tool shed repository.
- Don't allow repository names to be changed if the repository has been cloned at least 1 time.
-
More new tool shed features documented in the following new Galaxy wiki sections:
- Including proprietary data types that subclass from Galaxy data types in the distribution
- Including proprietary data types that use class modules contained in your repository
- Including datatype converters and display applications
- Automatic installation of Galaxy tool shed repository data types into a local Galaxy instance
- Getting updates for tool shed repositories installed in a local Galaxy instance
- Migrating tools from the Galaxy distribution to the Galaxy main tool shed
- Configuring your Galaxy server to automatically install tools eliminated from the Galaxy distribution
- Use case: automatically install the Emboss tools and datatypes into a local Galaxy instance
