Fwd: Exome Sequencing Analysis
by Johnathan Cooper-Knock 08 Oct '13

08 Oct '13

Hello, My name is Johnathan Cooper-Knock, I am a clinical fellow based at the University of Sheffield, UK. I am trying to use Galaxy for analysis of DNA sequencing data and I have run into a problem. I am trying to run the SAM/BAM Hybrid Selection Metrics step on Galaxy (part of the Picard tools) but I can't find bait and target bed files that Galaxy will accept. My library capture was performed using the Aglilent All Exon V4 kit and I have uploaded the 'S03723314_Regions.bed' and 'S03723314_Covered.bed' files from ' https://earray.chem.agilent.com/suredesign/search.htm' but Galaxy does not even seem to recognise them as options for entry. Is this a formatting issue? Do you know where I can get ready formatted files? Thanks Johnathan

galaxy cloud: location of imported and converted fastq's
by p Vedell 07 Oct '13

07 Oct '13

Hi, I had fastq.gz files in an Amazon S3 bucket. I created a Galaxy on the Cloud instance using CloudMan. I used GetData and pasted in the url's of the fastq.gz files into Galaxy on the Cloud. They were successfully imported into the session and converted to fastq's, it seems. However, at the next step (fastq groomer), Galaxy on the Cloud appears to expect that the imported and converted fastq files are in the same S3 bucket where the fastq.gz files were. But, they are not there. I read somewhere in documentation or notes that the data is actually in /mnt/galaxyData folder. However, I am not sure how to point fastq groomer to this place in the web interface or alternatively, I am not sure how to move the fastq's back to the s3 bucket (w/o downloading and re-uploading which would be very time-consuming). Thanks for any help you can provide. PT

Re: [galaxy-user] Metagenomic filtering
by Scott Tighe 06 Oct '13

Dear Jing What you have outlined below is perfect. I wonder how hard it would be to design a few filters that only look a certain genes and or filter model organisms out of the dataset. For example, say you want only data for 16s or only gyrase, but no /E.coli/ and no /Pseudomanas aeroginosa/ Scott Scott Tighe Senior Core Laboratory Research Staff Advanced Genome Technologies Core University of Vermont Vermont Cancer Center 149 Beaumont ave Health Science Research Facility 303/305 Burlington Vermont 05405 802-656-2557 On 9/25/2013 12:06 AM, Jing Yu wrote: > Hi Scott, > > My first thought is: > > 1.

add nglims to galaxy-dist
by Peter Huang 04 Oct '13

04 Oct '13

Hi Brad, I am curious if you could tell me the way that I could add your nglims to my galaxy-dist production system. I have read your step by step procedure here: http://wiki.galaxyproject.org/Admin/Sample%20Tracking/Next%20Gen but it didn't mention how to add it to the galaxy-dist. Do you have a patch name for it? Should I use hg pull or hg patch? Thanks Best, Peter

Can TopHat take SNPs into account?
by Hoang, Thanh 03 Oct '13

03 Oct '13

Hi, I have been mapping my RNA-seq data to mouse genome from a different mouse strain using TopHat. I am wondering whether TopHat can take SNPs into account during the alignment? ( using SNPs track as an optional input)? Thanks Thanh

Hi all, I am trying to perform TopHat for Illumina from Galaxy's Main Server, and it is in queue for the past 3 to 4 days. Is this normal? Thanks & Regards,Kumar.

queue rules for multi-step workflows
by zuzmus 03 Oct '13

03 Oct '13

Dear Galaxy managers, I would like to ask about the queuing rules for the workflows before processed on the server? I use my customized Galaxy workflow which contains 22 following steps (basically, filtering, trimming and format change of NGS data). I guess the server is generally very busy during last weeks/months (?), so my job was waiting about 24 hours in a queue (which would not be a problem), and then the first step of the workflow was processed, but the following 21 is again/still waiting (already for another couple of hours...). It makes me wondering about the queuing rules because I expected that the whole workflow is queued as one job.. Then my question is if the whole workflow, once submitted, is listed in the queue, or does the following step queue only after the previous step is finished (which would mean to wait the whole queue for each step of the workflow...)? I routinely used those wrokflows before (months ago) without any problems... I tried to search similar question in the archive before I posted this one... Thanks a lot for your answer, My best Zuzana Musilova -- Zuzana Musilova, PhD. (zuzmus(a)gmail.com) Zoological Institute University of Basel Vesalgasse 1, CH-4051 Basel Switzerland - Europe

URL problem
by Kucukural, Alper 03 Oct '13

03 Oct '13

Hi, I have a problem in galaxy to get host/domain name in two different pages. First one is in the tool installation from toolshed, I got the error below, ##### Not Found The requested URL /admin_toolshed/prepare_for_install was not found on this server. ##### The second one is in the saved histories. When I click the buttons of the saved histories. I got the similar error like below. ##### Not Found The requested URL /history/list was not found on this server. ##### I haven't seen these any other pages yet. My installation is working on LDAP authentication with Proxy. So, I could not find a place to set the domain or host name in these two places that they can actually find the requested URLs. In the paster.log file. I don't get any error when I install a tool or go to another history. It doesn't report any error. Thanks for your help, Alper Kucukural
