Tool without input parameters
by Jelle Scholtalbers 15 Jan '10

15 Jan '10

Hi, Is there a way to provide a tool through galaxy that doesn't need any input parameters? If I just don't specify a parameter I get an error: "AttributeError: Tool instance has no attribute 'inputs'" Specifying a hidden input parameter will load the xml, but in galaxy it won't show a tool overview or execute the tool for you when you click on its name. Cheers, Jelle

Is there any way to calculate % AT or GC of a group of sequences?
by Noa Sher 13 Jan '10

13 Jan '10

I am looking at a file of peaks from ChIP-chip data and would like to know whether there is a way to take all the sequeneces associated with these peaks and to calculate the total %AT and %GC, to see if there is enrichment compared with the entire genome? Thanks Noa

Re: [galaxy-user] Suggestion on functionality for published workflows
by Jeremy Goecks 12 Jan '10

12 Jan '10

Hi Assaf, I'm cc'ing the galaxy-user list because this is a good discussion to have and because this is good information to share. To your questions: > I make a history 'importable via link' and it appears on the public list, but what's now ? > how does somebody else import it ? there's no clickable URL or button. First, to be clear: we've not broken/replaced/removed any functionality with any recent changes; these changes provide enhancements. I assume we're starting from the history grid. When you make a history importable from the grid, you can see the link to its public location by clicking on the text "importable" in the history's status column. This link takes you to a page where you can see two links for each importable history: a link for importing the history and a link for viewing the history. The view link takes you to a page where you can view the history *or* import the history (there's a link at the top of the page to import it). > Also, > will there be a way to make a history importable but *not* public ? > I use the 'import' link a lot, but I don't want to make my histories public for everyone. This is a difficult issue and one that's in flux and open for discussion. Right now, when you make a history importable, it is public in the sense that anyone can import it. Yes, they have to know the history's encoded ID, but "security through obscurity" is not a model that Galaxy employs. If someone wants to share a history with a limited subset of people and keep the history private, they can do so via the history sharing mechanism. Because "enable import" already makes a history accessible by everyone, it is reasonable that doing so makes the history "public." The basic sharing categories, then, haven't changed. What's changed, of course, is that Galaxy now makes it possible to find public/importable items. As I said, we're in the process of changing the history sharing language to make clearer what is happening; hopefully these changes will help users decide when to make a history public and when to share it with a limited set of other people. Another option is to allow users to make a history public but hide it from the list of public items. This is effectively what making a history importable does, and it's not a great solution. FYI, there are distinct advantages when users can view a history rather than having to import it: (a) it's less work to view the history; (b) it's not necessary to clutter your histories with imported histories; (c) it's not necessary to understand how to use Galaxy to view a history; and (d) users can (eventually) annotate/rate/comment on shared/public histories, thereby providing a single place to work with a shared history.

Suggestion on functionality for published workflows
by Timothy Hughes 12 Jan '10

12 Jan '10

I have heard from jgoecks <http://bitbucket.org/jgoecks/> that the galaxy team are working on a repository for all galaxy objects. I would like to suggest that all workflows that are shared publically (published) have a mandatory field that briefly describes their functionality and that the repository have search functionality which enables a search of published workflows using this field. I am sure their are loads of great workflows out there which are either immediately usable or are easily adaptable. Getting access to such workflows would also be an excellent way to learn Galaxy in a complementary way to the screencasts. While we are waiting for such functionality, perhaps Galaxy developers could set up a simple page where the public histories / workflows can be posted. The simplest solution might be just a check box on the sharing page ("post link to publicly accessible page"), alternatively just a piece of text on the sharing page encouraging users to manually post on specific forum or mailing list.

Fetching promoters
by Linda Barnum 08 Jan '10

08 Jan '10

Hello, Is there a way to fetch the promoter regions for homologous genes from different species. E.g. say I'd like to fetch the promoter region for a drosophila gene CG13222 from drosophila as well as its CG13222 homologues in other flies from UCSC genome browser? Thanks, Lin

06 Jan '10

Hello all, GMOD will once again have a strong presence at the Plant and Animal Genome Conference (PAG 2010), being held January 9-13 in San Diego. There will be over 45 talks, workshops, demonstrations and posters about GMOD Components and projects that use them. This includes a workshop on Galaxy: Animal Genomics With Galaxy: Analyze, Publish, And Visualize Saturday, Jan 9, 1:30-2-30, California Room Anton will be presenting the workshop. See the PAG 2010 page on the GMOD wiki for a full listing and a flier showing highlights: http://gmod.org/wiki/PAG_2010 If you are attending PAG, please consider going to this and the other GMOD-related presentations. Thanks, Dave C. -- Please keep responses on the list! http://gmod.org/wiki/January_2010_GMOD_Meeting http://gmod.org/wiki/GMOD_News Was this helpful? http://gmod.org/wiki/Help_Desk_Feedback
