substitute or replace a value?
by David Hoover 26 Apr '11

26 Apr '11

Is there a tool for doing a global or column-based substitution in a text or tabular file? For example, replace all instances of the number 2 in a column to a number 1? David Hoover Helix Systems Staff http://helix.nih.gov

DB access and passowrd field
by Bossers, Alex 25 Apr '11

25 Apr '11

Hi All, I have some tools that generate some tabular output. The next step is to aggregate the data for some filtering and analysis. In my view the best way to do by using a DB (MySQL in my case). Tools and cmd line wrappers can easily connect to this DB (another database than galaxy is using of course) when providing the details for access like address:port, username and password. Is there any way to embed a text field for a galaxy tool that is of type password or blinded? Don't want to share user specific login details when sharing histories or galaxy pages.Or is this a bad thing to pursue anyway? Thanks for any directions. Alex

Could anyone body tell me why our C program do not work in galaxy
by liyanhui607 22 Apr '11

22 Apr '11

Dear Sir, We have a program writen in C lanuage. It can run nomally in linux environment. We plan to add it to galaxy, but it did not work. The C file after complie named "shortest-path" The shortest-path.xml is as follow: Could anybody tell me what is wrong ? why it does not work? Thank you very much! Best Wishes! Yan-Hui Li <tool id="shortest_path_1" name="shortest_path"> <command interpreter="C">./shortest_path $infile1 $output </command> <inputs> <param format="text" name="infile1" type="data" label=" expressed_genes_20101024.hprd8_biogrid-2.0.58.adj_matrix.txt "/> </inputs> <outputs> <data format="tabular" name="output" /> </outputs> <tests> <test> <param name="input" value="1"/> <param name="input" value="../GEO_dataset/expressed_genes_u133a.6k_u133p2.8k_20101024.txt"/> <param name="input" value="../ppi/hprd8_biogrid-2.0.58.ppi.txt"/> <output name="out_file1" file="expressed_genes_20101024.hprd8_biogrid-2.0.58.ppi.txt"/> </test> </tests> </tool>

NLStradamus wrapper (for nuclear localization signals)
by Peter Cock 22 Apr '11

22 Apr '11

Hi all, I just wanted to mention (to avoid duplicate work) that I have a working Galaxy wrapper for NLStradamus v1.6, a tool for prediction of nuclear localization signals (NLSs) from a protein FASTA file. The wrapper does a little reformatting of the output to get a clean tabular file for use in Galaxy. I would release this to the Galaxy Tool Shed now, but the tool's author Alex Nguyen Ba tells me he hopes to have an update released fairly soon which should include a native tabular output - probably with a richer column structure. So rather than having to change the tool output and potentially break workflows, I plan to wait till then. However, if anyone wants the wrapper before then, drop me an email. Regards, Peter References: A. N. Nguyen Ba, A. Pogoutse, N. Provart, A. M. Moses. NLStradamus: a simple Hidden Markov Model for nuclear localization signal prediction.

Galaxy tools' priority level (nice)
by Peter Cock 22 Apr '11

22 Apr '11

Hi all, Our Galaxy is running on a shared server which will sometimes be running other computationally demanding jobs (outside of Galaxy). In some cases I'd like these to have priority, perhaps by having Galaxy run the tool child processes at a nice level of 10 (say). Is there any built in way to control the Unix priority level (e.g. nice or ionice) used to run tasks? I don't see anything on here, but perhaps I'm looking in the wrong place: https://bitbucket.org/galaxy/galaxy-central/wiki/Config/WebApplicationScali… Thanks, Peter

Thanks for the details - it looks simple enough to add here too. If/when any SVG producing tools are added to Galaxy or the Galaxy Tool Shed, then it would be nice to have this done in the main repository. >>> The nice benefit of SVG in addition to not needing a plugin is >>> that the image can scale with the surrounding text if you zoom >>> in your browser (without loosing resolution). >>> >>> The disadvantage is that although my users know what a PDF >>> file is and can process them for posters/manuscripts, most of >>> them never heard of SVG and get stuck when it doesn't import >>> into PowerPoint et al. :( >> >> Do they cope with PDF? > > Well, they know how to view and print one :).

Still a hassle, but > they manage... Getting a PDF into PowerPoint or Word is easy on a Mac ;) But yes, point taken - even though a PDF is easier to work with than an SVG (or a postscript file), it can still be a hassle. Peter

Access control for galaxy
by Raghuraman Ramamurthy 21 Apr '11

21 Apr '11

Hello, I would first like to thank and appreciate the Galaxy team for their efforts. I want to clone galaxy and host it in my website. In doing so, I want to restrict the users who use galaxy on my website. So, is there any access control module which could be integrated with galaxy, to make it secure and grant access to only a set number of people. Thanks, Raghu

Sample Tracking: How datasets are transferred from Sequencer to Galaxy
by Joe Cruz 20 Apr '11

20 Apr '11

Hello, I was hoping someone could explain the process of how a dataset is transfered from a configured Sequencer to a Galaxy library within sample tracking. Particularly how RabbitMQ, API keys, transfer_manager_port and enable_sequencer_communication (in universe_wsgi.ini file) work in this process. Your help is greatly appreciated! Thanks Joe A. Cruz
