Groovy tool for galaxy
by Anshul Tak 23 Aug '17

23 Aug '17

Hi, I have a question regarding galaxy. Can I execute groovy scipts using galaxy? I installed groovy in galaxy docker image and all the dependencies. However, when I try to execute a tool which require groovy engine it says "/export/galaxy-central/database/job_working_directory/000/2/tool_script.sh: line 9: groovy: command not found" So I understood the error that galaxy is not able to find groovy but ideally it should take the groovy engine as it is installed. Can you give me some pointers to solve this issue? -- With Regards, Anshul Tak

DeepTools installation error
by Timo Janßen 05 Jul '17

05 Jul '17

Hi all, trying to install the deeptools_suite from the toolshed I only get the following error: "500 Internal Server Error nginx/1.11.10" This happens as well for the dependencies, e.g. deeptools_bigwig_compare. I am currently using Galaxy 16.10 with nginx proxy. Also the installation of the dependency package_python_2_7_matplotlib_1_4 fails because of a missing dependency: "Error installing tool dependency python version 2.7.10: Unable to locate required tool shed repository named package_python_2_7_10 owned by iuc with revision 80931fb5f433." Has anyone seen these problems before and knows a solution?

Pulsar - running as real DRMAA user problems
by Poole, Richard 13 May '17

13 May '17

Hey John, So I’ve been happily using Pulsar to send all my Galaxy server jobs to our cluster here at UCL for several months now (I love it!). I am now exploring the ‘run-as-real-user’ option for DRMAA submissions and have run into a problem. The files are correctly staged, correctly chowned, successfully submitted to the queue and the job runs. However, at job end (collection?) fails with the following error message in Pulsar: Exception happened during processing of request from (‘*.*.*.*', 54321) Traceback (most recent call last): File "/opt/rocks/lib/python2.6/site-packages/Paste-2.0.1-py2.6.egg/paste/httpserver.py", line 1072, in process_request_in_thread self.finish_request(request, client_address) File "/opt/rocks/lib/python2.6/SocketServer.py", line 322, in finish_request self.RequestHandlerClass(request, client_address, self) File "/opt/rocks/lib/python2.6/SocketServer.py", line 617, in __init__ self.handle() File "/opt/rocks/lib/python2.6/site-packages/Paste-2.0.1-py2.6.egg/paste/httpserver.py", line 446, in handle BaseHTTPRequestHandler.handle(self) File "/opt/rocks/lib/python2.6/BaseHTTPServer.py", line 329, in handle self.handle_one_request() File "/opt/rocks/lib/python2.6/site-packages/Paste-2.0.1-py2.6.egg/paste/httpserver.py", line 441, in handle_one_request self.wsgi_execute() File "/opt/rocks/lib/python2.6/site-packages/Paste-2.0.1-py2.6.egg/paste/httpserver.py", line 291, in wsgi_execute self.wsgi_start_response) File "/cluster/galaxy/pulsar/pulsar/web/framework.py", line 39, in __call__ return controller(environ, start_response, **request_args) File "/cluster/galaxy/pulsar/pulsar/web/framework.py", line 144, in controller_replacement result = self.__execute_request(func, args, req, environ) File "/cluster/galaxy/pulsar/pulsar/web/framework.py", line 124, in __execute_request result = func(**args) File "/cluster/galaxy/pulsar/pulsar/web/routes.py", line 82, in status return status_dict(manager, job_id) File "/cluster/galaxy/pulsar/pulsar/manager_endpoint_util.py", line 12, in status_dict job_status = manager.get_status(job_id) File "/cluster/galaxy/pulsar/pulsar/managers/stateful.py", line 95, in get_status proxy_status, state_change = self.__proxy_status(job_directory, job_id) File "/cluster/galaxy/pulsar/pulsar/managers/stateful.py", line 115, in __proxy_status proxy_status = self._proxied_manager.get_status(job_id) File "/cluster/galaxy/pulsar/pulsar/managers/queued_external_drmaa_original.py", line 62, in get_status external_status = super(ExternalDrmaaQueueManager, self)._get_status_external(external_id) File "/cluster/galaxy/pulsar/pulsar/managers/base/base_drmaa.py", line 31, in _get_status_external drmaa_state = self.drmaa_session.job_status(external_id) File "/cluster/galaxy/pulsar/pulsar/managers/util/drmaa/__init__.py", line 50, in job_status return self.session.jobStatus(str(external_job_id)) File "build/bdist.linux-x86_64/egg/drmaa/session.py", line 518, in jobStatus c(drmaa_job_ps, jobId, byref(status)) File "build/bdist.linux-x86_64/egg/drmaa/helpers.py", line 299, in c return f(*(args + (error_buffer, sizeof(error_buffer)))) File "build/bdist.linux-x86_64/egg/drmaa/errors.py", line 151, in error_check raise _ERRORS[code - 1](error_string) InvalidJobException: code 18: The job specified by the 'jobid' does not exist.

Also have rewrites set up in Galaxy’s pulsar_actions.yml and I am using remote_scp for the file transfers rather than http - although I have also tried switching back to http (as I noticed caching, which I am also testing, does not work with scp transfers) but get an identical set of error messages. As I say, I have no troubles using a regular queued_drmaa manager in pulsar. Any ideas what the problem may be?

Running jobs as real user and extra_file_path
by Louise-Amélie Schmitt 28 Apr '17

28 Apr '17

Hi everyone, I just wanted to ask how the extra_file_path is handled in case of job running as the real user since the file_path is only writable by the galaxy user. Any clue? Thanks, L-A

Testing updated NCBI BLAST+ wrappers for version 2.5.0
by Peter Cock 19 Apr '17

19 Apr '17

Hello all, I have updated the NCBI BLAST+ wrappers on the Test Tool Shed, the wrapper is now at v0.2.00: https://testtoolshed.g2.bx.psu.edu/view/devteam/ncbi_blast_plus/ The main changes is this now depends on BLAST+ 2.5.0, and that is available via either BioConda or the Tool Shed: https://toolshed.g2.bx.psu.edu/view/iuc/package_blast_plus_2_5_0/ https://testtoolshed.g2.bx.psu.edu/view/iuc/package_blast_plus_2_5_0/ In order for the dependency to work smoothly on both BioConda and the Tool Shed system, we have changed the package name from "blast+" to just "blast". Given the NCBI stopped updated the original "legacy" BLAST some time ago, when combined with the version number this is no longer ambiguous. Jumping from using BLAST+ 2.2.31 to using BLAST+ 2.5.0 required updating lots of the test files for NCBI changes, including dropping the GI numbers in many outputs, expanding the percentage identity field from 2dp to 3dp, and also changing how -parse_deflines works with tabular output. The wrappers (deliberately) do not yet offer any new functionality added in the recent NCBI BLAST+ updates, in particular BLAST XML v2 is not yet available as an output with a datatype in Galaxy. At this point I would welcome feedback from those of you using the BLAST+ wrappers - including if you were able to install this with the dependencies from BioConda or the traditional Tool Shed packages. Once I'm confident that this is all OK, I will update the main Tool Shed (and think about adding new functionality in 2017). Thank you all, Peter

Hi, is it possible to implement some kind of login for the usage reports webapp, so that only admins can see the website? In our current setup the tool is running on a server with many other users so that anyone who knows the port can open the website and see potentially sensitive data.

LDAP group data synchronization
by Matthias Bernt 30 Mar '17

30 Mar '17

Dear galaxy developers, I'm currently trying to establish galaxy at the UFZ research center in Leipzig. I have some questions on how to match the infrastructure of galaxy and and our local infrastructure. I would be really happy about some comments on my ideas. Galaxy external authentication via LDAP is already working -- worked like a charm :) How to integrate LDAP group data into galaxy? My idea would be to regularly sync the groups and user-group associations from LDAP to galaxy via the API/bioblend. Adding groups and user-group associations should be no problem, but how about removing users, groups, or associations? Are there any pitfalls that I need to consider? How about data associated with deleted users? Maybe there are already some scripts around that I could build upon? Best, Matthias P.S. I'm afraid that I ask quite a lot of questions at the moment. I hope that I will be soon able to contribute a bit. -- ------------------------------------------- Matthias Bernt Bioinformatics Service Molekulare Systembiologie (MOLSYB) Helmholtz-Zentrum für Umweltforschung GmbH - UFZ/ Helmholtz Centre for Environmental Research GmbH - UFZ Permoserstraße 15, 04318 Leipzig, Germany Phone +49 341 235 482296, m.bernt(a)ufz.de, www.ufz.de Sitz der Gesellschaft/Registered Office: Leipzig Registergericht/Registration Office: Amtsgericht Leipzig Handelsregister Nr./Trade Register Nr.: B 4703 Vorsitzender des Aufsichtsrats/Chairman of the Supervisory Board: MinDirig Wilfried Kraus Wissenschaftlicher Geschäftsführer/Scientific Managing Director: Prof. Dr. Dr. h.c.
