Re: [galaxy-dev] [galaxy-bugs] /tmp directory

Thanks for the answer! I've copied this response to the dev list email instead, after realizing its probably best there. I'm also having some trouble getting our PBS system configured. I have pbs://hostname/ as my pbs parameter in the universe file, as well as everything else specified in the documentation. I'm getting no error in the interface, and the backend never actually gets the job. The error I see in the logs says: galaxy.jobs.runners.pbs ERROR 2009-10-30 13:40:27,762 Uncaught exception queueing job Traceback (most recent call last): File "/home/perin/galaxy-dist/lib/galaxy/jobs/runners/pbs.py", line 144, in run_next self.queue_job( obj ) File "/home/perin/galaxy-dist/lib/galaxy/jobs/runners/pbs.py", line 219, in queue_job script = pbs_symlink_template % (job_wrapper.galaxy_lib_dir, " ".join(job_wrapper.get_input_fnames() + output_fnames), self.app.config.pbs_stage_path, exec_dir, command_line) TypeError: sequence item 1: expected string, DatasetPath found I'm guessing this has something to do with my config parameters, and the queue its trying to submit to. the pbs://hostname/ value was used under the assumption that it would default to the 'default' queue on our cluster, so I'm wondering if I need to hard code those values into the connection string? I'm a little confused as to how the syntax translates to the actual required string. My guess is, for our values: pbs://variome.chop.edu/default Perhaps its related to the scrambling of the egg instead? I simply passed LIBTORQUE_DIR to the directory containing my libtorqure.so etc... ? Thanks in advance.

Latest download from repository
by Dijk, F van 02 Nov '09

02 Nov '09

Hi, I have two questions to ask, firstly: We've experienced some errors with Galaxy lately so we decided to download the latest copy from your repository. After installing it, it seems like some tools like "mapping with Bowtie and BWA" are missing. When running run.sh it looks like they aren't loading properly. Yesterday we did also download from these repositories and we didn't experience these errors, so do you know what the problem can be? Second: What version of python do you use for Galaxy, because the older python versions we use seem to give some problems. I hope to hear from you soon.

toolpane info links
by Gunnar Rätsch 29 Oct '09

29 Oct '09

Hi there, I just talked with Anton at the Genome Informatics meeting about the possibility of including links to galaxy pages in the tools menu. This can be useful for describing a set of tools or even explaining the whole system. It would be useful to have these links on the top level as well as on the tool level. Would it be very hard to have more than one hierarchy in the tool menu? Thanks a lot! Gunnar
