November 24, 2010 Galaxy Development News Brief Here are the highlights of the following upgrade: hg pull -u -r 8729d2e29b02 http://bitbucket.org/galaxy/galaxy- central/wiki/Features/DevNewsBrief/2010_11_24 Galaxy's FTP Server New Data Upload Option * User how-to: http://bitbucket.org/galaxy/galaxy-central/wiki/UploadViaFTP * Configuration instructions for local installs: http://bitbucket.org/galaxy/galaxy-central/wiki/Config/UploadViaFTP OpenID Login * User how-to and config instructions: http://bitbucket.org/galaxy/galaxy-central/wiki/OpenIDAuthentication NGS Simulation Tool * Allows user to simulate multiple Illumina runs with several parameters that can be set. o On each run, one position is randomly chosen to be polymorphic and sequencing errors are also simulated. o The primary output is a png with two different plots. o The other output shows summary statistics about the simulation. * NGS simulation tool location: tools/ngs_simulation/ngs_simulation.xml Tophat and Cufflinks RNA-seq Tools * Addition of RNA-seq analysis tools Tophat and Cufflinks. o Together, these tools can be used to analyze RNA-seq data to understand alternative splicing and isoforms, gene and isoform expression, and perform statistical tests for differential expression. o Galaxy supports Tophat version 1.1.1 and later and Cufflinks version 0.9.1 and later. (These are the versions included this distribution). Import or Export Workflows & Histories * Workflows can now be downloaded/exported to a file and uploaded/imported into Galaxy, making it easy to move workflows between Galaxy instances. * Beta feature: Histories can also be downloaded or moved from one Galaxy instance to another, subject to these limitations: o history archives can be uploaded/imported only via URL, not file o histories must be shared in order for them to be importable via archive o tags are not currently imported o reproducibility is limited as parameters for imported jobs are not always recovered and set Even Better Data Visualization with Trackster * Trackster now supports interactive filtering for VCF quality values and BED score values. * For example, a user can drag a slider to filter a file of splice junctions to view junctions supported by different numbers of reads. trackster splice example * Improved CIGAR support to BAM display. Properly displays matches, deletions, skipped bases, and clipping. Padding for insertions are currently not represented in the display. * GFF feature blocks are now displayed correctly, along with name, strand, and score information. * General enhancements o Removed right-hand pane, allow inline re-ordering and configuration of elements o Moved navigational controls to the top o Histogram display for LineTracks and overview o New navigational slider and new overview settings under the dropdown corresponding to the track name o Summary view now shows maximum y-axis value o Can change draw color of LineTrack o When editing track config, "Enter" and "Esc" keys submit and cancel the changes, respectively o Don't index bottom level for summary_tree, greatly reducing computation time (>5x speedup) while not sacrificing usability Refactored to pass JSLint * Tuning o Fix ReferenceTrack issue. o Don't re-add new datasets when refreshing after using "Add into current viz" link. o To prevent browser lockup, only display up to 50 lines of features by default (user-editable in future). Coming soon: add warning message when this occurs. o Fix LineTrack rendering bug when more than one tile on screen. Native Data set Re-organization * Galaxy now uses a set of data tables instead of simple loc files to organize, document, and store native genome data sets. * Why Data tables? Better data management for long term stability! o Allows the information in the loc file, including the path, to be changed. o By using a unique ID as the parameter value, data links in existing workflows are preserved. * Most tools (PerM, Bowtie, BWA, Lastz, Megablast, SRMA, Tophat) that previously used loc files now have the new data tables organization implemented. * Better data tracking has allowed for more informative genome name display in tool dropdown boxes. * For local installations: o See the new wiki describing how to use data tables: https://bitbucket.org/galaxy/galaxy-central/wiki/DataTables o More help for NGS tool setup (update pending): https://bitbucket.org/galaxy/galaxy-central/wiki/NGSLocalSetup Sample Tracking * Complete re-write of the Framework and User interface (database schema unchanged). * New interactive interface to select files to transfer from the sequencer to Galaxy data libraries. * The data transfer feature now uses Galaxy RESTful API. * Full documentation detailing the new functionality and how to use it will be available within a few weeks through the home Galaxy Wiki. Instantiating Galaxy * New checkouts will now perform all necessary setup directly in run.sh, there is no longer a need to run setup.sh prior to run.sh. setup.sh will be removed in a future distribution). Analysis Tools * Enable 'FASTX-Toolkit for FASTQ data' as a subsection under 'NGS: QC and manipulation' in tool_conf.xml.sample/main. Includes special handling for when the shell only allows for strict Bourne syntax. * Add descriptive labels to output dataset names for MACS peakcalling tool. * Taxonomy tools updated for better error reporting. Includes special handling for when the shell only allows for strict Bourne syntax. * Refactor sam_bitwise_flag_filter tool, simplifying it and making it fastet when there are multiple flag criteria Tool Dependency Enhancements * Addition of the 'package' type to <requirement> tags in the tool config. 1 Syntax for tool configs is: <requirements> <requirement type="package" version="X.Y.Z">NAME</requirement> </requirements> 2 Next, a directory should be created, and the path to that directory should be set in universe_wsgi.ini as 'tool_dependency_dir'. 3 Galaxy will then source the following file prior to executing the tool's : <tool_dependency_dir>/<name>/<x.y.z>/env.sh 4 The 'version' attribute of the 'requirement' tag is optional and if left off, Galaxy will look for the following instead: <tool_dependency_dir>/<name>/default/env.sh Data Libraries * UI: new style for dropdown menus. * Now uses jStore to save folder expansion state. * Pre-generate and cache variables so that expensive functions like jQuery.siblings, jQuery.filter and jQuery.find only have to be called a minimum amount of times. Provides significant speedup to loading of large data libraries. Genome Indexes * Add basic support for Bowtie indexes as a datatype (bowtie_base_index, bowtie_color_index), available via datatype conversion. Currently, the indexes need to be converted manually from the FASTA file before use in Bowtie, but they can be reused. * A new sample loc file (tool-data/all_fasta.loc.sample) was added which lists fasta files. A script (scripts/loc_files/create_all_fasta_loc.py) was created that can be used to generate this loc file for local installations. Data Formats * New gff2bed tool to convert GFF3 files to BED. * Modified Filter and Sort -> Filter tool to operate correctly on files with a variable number of columns, such as in SAM files. * New datatype added: VCF (variant call format). Histories * Add descriptive labels to output dataset names for MACS peakcalling tool. * Add name/designation to HDA name for new datasets created in collect_primary_datasets. Workflow Tuning * Shift management of the interaction between workflow outputs and HideDatasetActions to the front end editor. * No usability changes, but this resolves the issue with multiple HideDatasetActions being created. * Existing workflows displaying multiple HideDatasetActions per step on the Run Workflow screen will persist. These extra HideDatasetActions are harmless, but a simple edit workflow -> save will remove them. * Workflow Inputs change: o Workflow inputs that aren't a subtype of text, were previously not an option. o Added 'data' datatype to registry, which will allow both text and binary inputs (and their subtypes) to workflow input steps. o Note that this will allow a user to change the datatype of something to 'data'. User Interface (UI) * New function for downloading metadata files associated with datasets (such as bai indices for bam files). See the Save icon drop-down menu. * Enable display of unicode characters in history and workflow annotations and when listing and running workflows. * Dynamicically generated popup-style menus. Greatly improves load time, especially for data libraries having potentially large menu. * Labels next to checkboxes can now be clicked to check the corresponding box. * Radio boxes in tool forms now also have clickable labels as well. * New style for search boxes in grids. Grid items will no longer show outline when hovered upon if there are no actions to be performed. * Refactored refresh_on_change javascript code to run in galaxy.base when the page is loaded. * Remove the creation of a background element that closes the active menu clicked. Instead, bind an event to close active menus to the document object of current and all other framesets. Tested in IE. * Make links in split menu buttons "go through" instead of popping up the menu options. General * Functional Test Framework: new nose plugin that shows a diff between tests failed this time and last time. * Documentation update to add more options added to the sample config file. Bug Fixes! * Fix for TextToolParameter.get_html_field when provided value is an empty string but default value specified in tool is non-empty string. Fixes issue with rerun button where if a user had input an empty string, the form displayed when rerun would have the default value from the tool and not the actual previously specified value. * Fix for Integer/FloatToolParameter.get_html_field() when 'value' is provided as an integer/float. Fixes an issue seen when saving workflows: If an integer or float tool parameter is changed to a value of 0 or 0.0 and saved, the form field would be redisplayed using the default tool value; and not the value that is now saved in the database. * Fix for setting columns in workflow builder for ColumnListParameter. e.g. allows splitting lists of columns by newlines and commas and strips leading 'c's. * Fixes for rerun action to recurse grouping options when checking unvalidated values and cloned HDAs. Better selection of corresponding HDAs from cloned histories, when multiple copies exist. * Have rerun action make use of tool.check_and_update_param_values(). Fixes Server Error issue when trying to rerun updated tools. * Fix for display framework to work with workflows that contain tools that have been updated. Previously, this would cause a server error when trying to view a workflow or a page with an embedded workflow that contained an updated tool. * Fix bug that was causing Page item selection grids to be initialized twice and hence causing grid paging to fail. * Add some space between adjacent embedded items on Pages. * Fix path to closebox.png image so screencast close button is shown correctly. * Fix the Admin -> Manage Jobs interface when using multiple Galaxy processes * When possible (e.g. Python >= 2.6), don't use tons of memory to handle zipped uploads. * Fix cluster stdout/stderr handling that could cause excessive memory usage if stdout/stderr were very large. * Make the PBS runner actually stop jobs when a user deletes output. This would only work before if the Galaxy user was a PBS "operator" and only using a single process setup. * Cause waiting jobs to fail if any of their inputs fail to set metadata correctly. * Fix 'import from current history' for Data Libraries that was showing metadata files that are not visible. Fix this same issue for 'Copy history items' feature. * DRMAA runner now uses get_id_tag() in Wrapper instead of job_id directly for creation of .sh .o and .e files, as well as some debugging. * Prevent Rename Dataset Action from allowing a blank input.
