samtools BAM to SAM tmp directory
by Matt Shirley 03 Jul '13

03 Jul '13

Is there a reason that the samtools BAM to SAM does not respect the new_file_path set in the config file? The tmp directory handling by different tool wrappers seems to be an issue right now on systems with small system tmp directories. -- Matt Shirley Ph.D Candidate - BCMB Pevsner Lab <http://pevsnerlab.kennedykrieger.org/> Johns Hopkins Medicine

Issue with set_user_disk_usage.py and Postgres 8.x
by Lance Parsons 06 Jun '13

06 Jun '13

The recent updates to set_user_disk_usage.py for Postgres users have an issue with Postgres 8.x. The SQL in the pgcalc method (line 51) leads to the following error: sqlalchemy.exc.ProgrammingError: (ProgrammingError) column "d.total_size" must appear in the GROUP BY clause or be used in an aggregate function LINE 4: FROM ( SELECT d.total_siz... ^ The problem is that version of Postgres before 9.x were a bit more restrictive in the use of GROUP BY.

Displaying genomic sequences in Trackster
by Naharajan Lakshmanaperumal 24 May '13

24 May '13

Dear all, We have our own galaxy instance and the idea is to have trackster enabled for users to be able to visualize NGS mapping. We were able to configure trackster in our instance and the visualization works fine. We have two questions regarding trackster: 1) We can't display genomic sequences in trackster. As per the tutorial, we set the location of the .2bit file in the twobit.loc file for the trackster to be able to display the genomic sequence but for some reason it doesn't display it. The name of the builds is the same in all places i.e) in ucsc/chrom/builds.txt and also in the .loc files. Any ideas on what else should be done? 2) While saving the visualization, there is always an error message saying "could not save visualization" and it doesn't seem to be a web browser issue. How do we then save the visualization? Thanks in advance, Naharajan

Difficulties using <repeat> tagset with min attribute
by Cory Spencer 08 May '13

08 May '13

Hi all - I've been trying to get the <repeat>...</repeat> tag working with a min attribute for some time now, though without any success. It works in other tools distributed with Galaxy, but when I attempt to use it in one of our custom tools, it dies with a "AttributeError: 'ExpressionContext' object has no attribute 'keys'" exception. Can anybody offer any insight? The full traceback is: ⇝ AttributeError: 'ExpressionContext' object has no attribute 'keys' URL: http://localhost:8080/tool_runner?tool_id=scde-list-compare Module weberror.evalexception.middleware:364 in respond view >> app_iter = self.application(environ, detect_start_response) Module paste.debug.prints:98 in __call__ view >> environ, self.app) Module paste.wsgilib:539 in intercept_output view >> app_iter = application(environ, replacement_start_response) Module paste.recursive:80 in __call__ view >> return self.application(environ, start_response) Module paste.httpexceptions:632 in __call__ view >> return self.application(environ, start_response) Module galaxy.web.framework.base:160 in __call__ view >> body = method( trans, **kwargs ) Module galaxy.web.controllers.tool_runner:68 in index view >> template, vars = tool.handle_input( trans, params.__dict__ ) Module galaxy.tools:1320 in handle_input view >> state = self.new_state( trans ) Module galaxy.tools:1248 in new_state view >> self.fill_in_new_state( trans, inputs, state.inputs ) Module galaxy.tools:1257 in fill_in_new_state view >> state[ input.name ] = input.get_initial_value( trans, context ) Module galaxy.tools.parameters.grouping:100 in get_initial_value view >> rval_dict[ input.name ] = input.get_initial_value( trans, context ) Module galaxy.tools.parameters.basic:1016 in get_initial_value view >> return SelectToolParameter.get_initial_value( self, trans, context ) Module galaxy.tools.parameters.basic:785 in get_initial_value view >> if self.need_late_validation( trans, context ): Module galaxy.tools.parameters.basic:1022 in need_late_validation view >> if super( ColumnListParameter, self ).need_late_validation( trans, context ): Module galaxy.tools.parameters.basic:766 in need_late_validation view >> for layer in context.itervalues(): Module UserDict:116 in itervalues view >> for _, v in self.iteritems(): Module UserDict:109 in iteritems view >> for k in self: Module UserDict:96 in __iter__ view >> for k in self.keys(): AttributeError: 'ExpressionContext' object has no attribute 'keys'

Conditional tool options based on input file format?
by Peter Cock 06 May '13

06 May '13

Dear all, I've looked over the wiki and as far as I can see, 'when' tags used inside 'conditional' tags only work on another input variable's values. I would like to be able to do is a conditional based on the file format of an input file. For instance, a tool might take XML or tabular files, and need to show additional parameters for one input type but not the other. Does this enhancement idea seem useful? Peter

Puzzling test failure with data_column parameter
by Peter Cock 24 Apr '13

24 Apr '13

Hi all, I'm working on a FASTA filter script, as per this email: http://lists.bx.psu.edu/pipermail/galaxy-dev/2010-November/003819.html Current code here: http://bitbucket.org/peterjc/galaxy-central/src/c3ac6d7a02f7/ I've added a basic test, but it won't run (see output below). I think the interesting bit of the error output is this exception: cannot find value/label "blastp_four_human_vs_rhodopsin.tabular" in list control, coming from function set_form_control_value in the twill.utils module. This is something to do with the columns parameter, a multiselect option referencing the columns in this tabular file. Removing the validator makes no difference. However, if I change the columns parameter to a plain text parameter, the test passes: $ hg diff diff -r c3ac6d7a02f7 tools/fasta_tools/fasta_filter_by_id.xml --- a/tools/fasta_tools/fasta_filter_by_id.xml Tue Nov 23 11:37:35 2010 +0000 +++ b/tools/fasta_tools/fasta_filter_by_id.xml Tue Nov 23 14:03:31 2010 +0000 @@ -4,9 +4,7 @@ <inputs> <param name="input_fasta" type="data" format="fasta" label="FASTA file to filter on the identifiers"/> <param name="input_tabular" type="data" format="tabular" label="Tabular file containing FASTA identifiers"/> - <param name="columns" type="data_column" data_ref="input_tabular" multiple="True" numerical="False" label="Column(s) containing FASTA identifiers" help="Multi-select list - hold the appropriate key while clicking to select multiple columns"> - <validator type="no_options" message="Pick at least one column"/> - </param> + <param name="columns" type="text" label="Column(s) containing FASTA identifiers" /> </inputs> <outputs> <data name="output_pos" format="fasta" label="With matched ID" /> I've tried searching the provided wrappers for similar examples (column multi-select from a tabular file). I found filters/uniq.xml (works but uses a bed file rather than a simple tabular file) and stats/cor.xml (needs R and rpy which I don't have installed yet) which have tests, and finally plotting/bar_chart.xml which has no unit tests. Would someone familiar with the internals of the Galaxy tests and how they set tool parameters be able to try reproducing this for me? The branch has all the unit test files required, and there are no new dependencies needed.

Hi, Can Galaxy resubmit a job if the node where the job is running fails? I know sge can do that by using qsub -r. It should be very useful if Galaxy can do that. Thank you, Cai

Composite datatype output for Cuffdiff
by Jim Johnson 06 Mar '13

06 Mar '13

Checking to see if there is any interest in including a parameter option to select outputs for cuffdiff, potentially including a composite output and a cummeRbund sqlite database. Issues: cuffdiff produces 21 output files, which is a little unwieldy in a galaxy history. cummeRbund generates its database when given a cuffdiff output directory, but manually hooking up 21 outputs to the cummerbund_wrapper is a pain. I've put demo code in the testtoolshed under the name repository name cummerbund http://jjohnson@testtoolshed.g2.bx.psu.edu/repos/jjohnson/cummerbund This includes new datatypes defined in datatypes_conf.xml and implemented in cuffdata.py:  <datatype extension="cuffdata" type="galaxy.datatypes.cuffdata:CuffDiffData"/>  <datatype extension="cuffdatadb" type="galaxy.datatypes.cuffdata:CuffDataDB"/> The cuffdiff wrapper has a multiple select parameter to choose which output files to put in the history. In addition to the 21 cuffdiff outputs, the wrapper can also generate: cuffdata - which is a composite HTML output with links to the 21 cuffdiff outputs cuffdatadb - which is the cummeRbund SQLite database I also added utility tools: cuffdata_datasets - which will take files from the composite cuffdata and copy them as datasets into the history cuffdata_cummerbund - which generates the cummeRbund cuffdatadb from the composite cuffdata I updated the cummerbund_wrapper: with tryCatch so that a R error on a plot won't exit the Rscript to include a small image of each plot on the html page added plots for : dispersion, scatter matrix, MDS, and PCA Thanks, JJ

Tabular file metadata - columns names
by Peter 22 Feb '13

22 Feb '13

Hi all, I'd like to know more about Galaxy's column metadata for tabular files. In the workflow editor under "Edit Step Actions" you can pick "Assign Columns", and then give column numbers for five predefined cases: Chrom, Start, End, Strand, Name. Do these "named columns" get shown anywhere in the Galaxy UI? For example, in a column select parameter widget? Is it possible to assign these columns in a tool's wrapper XML file? >From http://bitbucket.org/galaxy/galaxy-central/wiki/ToolConfigSyntax I'm aware of the metadata_source attribute to *copy* the meta data from the input file, but that isn't always relevant. Can I somehow specify that my tool has tabular output where column 1 is "Name"? Is it possible to introduce additional column types? e.g. "evalue" or "Description". Thanks, Peter

environment variables and paths for toolshed tools
by David Hoover 20 Feb '13

20 Feb '13

Are there any environment variables that are honored by toolshed installed tools? I tried creating a tool that uses ${GALAXY_DATA_INDEX_DIR} or $GALAXY_HOME, then uploaded it the test toolshed, then installed it automatically. Neither of these resolved to what I expected. I don't want to hard-code the path in the xml tool file, but rather have a default location for other executables and jar files. How should this best be done? David Hoover Helix Systems Staff
