workflow support in local instance
by Michael Rusch 28 Aug '08

28 Aug '08

I checked out galaxy from subversion today and installed it on a server here. I'm not seeing any workflow support through the interface. Is there something that needs to be done to enable it? Is the svn repos out-of-date? Am I missing something? Michael

newbie questions
by Michael Rusch 21 Aug '08

21 Aug '08

We're strongly considering switching to Galaxy from a piece of home-built software that we're in the process of developing. So, I have a couple of newbie questions to see what people's experience is. How does Galaxy scale? Does anybody have experience with scaling to thousands of datasets, or working with datasets in the hundreds of megabytes? We have traditionally done most of our work using a MySQL backend. I haven't (yet) received the green light from our sysadmin to install Postgres, and I'm wondering if anybody has any experience running on MySQL. Is it possible? Are there pitfalls? Has anybody by any chance implemented support for condor as a job scheduler? I think that's it for now. Thanks, Michael

Michael, I don't have any experience with Condor, but we're finding that the Galaxy framework scales very well - mostly because it doesn't do any of the computationally intense stuff itself - it hands that off through the job runner. Our internal Galaxy works fine with very large (6k subjects, Affy 6.0 snp chips, 9.6k subjects, Affy 5.0 snp chips...) datasets. Tools take a while to run (!) but Galaxy itself is more or less indifferent to the size of files because it only stores references (paths eg) to the disk files in the database - not the actual gigagobs of data. A collection of 100gb files takes about the same space in the Galaxy database tables as a collection of 1k ones as far as I can tell. A user's experience of Galaxy tool operation will obviously be impacted by the effects of physically shuffling large datafiles around for the cluster backend when a tool is run, so the cluster architecture, and the way datasets are made available to cluster nodes for processing is a key issue for very large datasets I suspect. On backends, I believe the party-line is that both PostgreSQL and MySQL are fully supported. We've used MySQL as our backend for nearly 2 years without any problems with released Galaxy versions - all 3 database backends are now all auto-tested before release AFAIK. Arguably, Postresql might be a better choice technically, and operationally, that's what runs the primary Galaxy site so is likely to work! My group remain familiar and comfortable with MySQL and don't have the energy to swap over. If you were going to swap, do it before you build a large userbase unless you have a bored DBA available to unload and reload a set of Galaxy history and user tables mid-stream.

megablast
by Ali Tofigh 18 Aug '08

18 Aug '08

I have a large set of short reads (from human) that I'm trying to analyze with galaxy. Specifically I want to map my nucleotide sequences to the human genome. I found the "short read analysis" section of galaxy. However, I can't seem to find any information on how to interpret the output from megablast. Could someone tell me what the numbers in the different columns represent? And when chosing target databases, what is "nt" and "wgs"? Thanks in advance, /Ali

[GALAXY] Galaxy Workflows are Here
by Anton Nekrutenko 18 Aug '08

18 Aug '08

Dear Galaxy User: Galaxy has just been upgraded with the most radical feature since its conception. It now features WORKFLOWS! Now you can: 1. Construct workflows by example ================================= Suppose you have just performed an analysis and now you want to re- run it again, modify its parameters, or use different input datasets. Previously (15 min ago) you would have had to redo it again. But now you can simply convert you existing history into a workflow! Watch how to construct workflow from a history here: http://screencast.g2.bx.psu.edu/galaxy/WorkFlow_SC4/ Watch how to modify workflow's parameters here: http://screencast.g2.bx.psu.edu/galaxy/WorkFlow_SC5/ 2. Construct workflows from scratch =================================== Galaxy now features an interactive workflow editor where things can be dragged around and connected. Watch how here: http://screencast.g2.bx.psu.edu/galaxy/WorkFlow_SC7/ 3. Make custom tools out of workflows ===================================== If you have a workflow that you want to use over and over again, you can now put it on the tool menu. Watch how here: http://screencast.g2.bx.psu.edu/galaxy/WorkFlow_SC6/ Finally, if you collaborate with someone, just share your workflows with that person. It is as easy as sharing histories. Workflows are in beta --------------------- Workflow support is currently in beta testing. Workflows may not work with all tools, may fail unexpectedly, and may not be compatible with future updates to Galaxy. If you encounter abnormal behavior, e-mail us to galaxy-bugs(a)bx.psu.edu.

New Tool Question - how to copy meta data from input to output?
by Assaf Gordon 18 Aug '08

18 Aug '08

Hello, I'm writing a tool which accepts interval files and output interval files. The input file has the metadata set (chr/start/end columns). How can I copy the metadata to the generated output file? Currently, the output file's metadata is always set to chrom=1, start=2, end=3 (which I guess is the default for BED format). Other galaxy tools do it, so I'm sure it's possible. Which python code is responsible for that (to be included in my tool's XML) ? Thanks, Gordon.

Problems upgrading to mercurial
by Assaf Gordon 06 Aug '08

06 Aug '08

Hello, I'm trying to upgrade an existing galaxy installation to use mercurial, and experiencing some problems. In one directory (called "galaxy_devel_old") I've got the old galaxy code base, updated to SVN revision r2771. On another directory (called "galaxy_devel") I've got the new galaxy code base, which was created using: $ hg clone http://www.bx.psu.edu/hg/galaxy galaxy_devel Both installations use the same configuration files, the same postgres database, and the same 'database/files' directory. The old galaxy works fine. With the new galaxy, I get the following SQL error (at the bottom of the text log): ----------------- URL: http://tango:8081/root/history File

Galaxy source repository change
by Nate Coraor 05 Aug '08

05 Aug '08

Hello, If you simply use the Galaxy Main or Test sites hosted at PSU, you can safely ignore this message. It pertains to people who've checked out their own copy of Galaxy for development or local use. Galaxy development has recently moved source control systems, from Subversion to Mercurial. This means that anyone using a local copy of Galaxy will need to make some changes to be able to download future updates. The preferred method of obtaining Galaxy source is through Mercurial directly (the 'hg' command): hg clone http://www.bx.psu.edu/hg/galaxy galaxy_dist Tarballs are also available via the zip/gz/bz2 links here: http://www.bx.psu.edu/hg And the repository is mirrored in Subversion here: svn co http://www.bx.psu.edu/svn/galaxy galaxy_dist Unfortunately, modifications to local copies of Galaxy will need to be transferred from your old checkout to the new checkout. Please let us know via <galaxy-bugs(a)bx.psu.edu> of any issues. Thanks, and thank you for using Galaxy. --nate

Importing features from BioMart

Hello, I would like to import features from BioMart into galaxy. However the 'embedded' BioMart view yields an HTML table. How do I convert that to GFF or BED?
