unable to import run or save-to-file published workflow after galaxy upgrade
by McCulloch, Alan 11 Oct '13

11 Oct '13

dear all, we've just upgraded our Galaxy server (Galaxy revision 7148:17d57db9a7c0, upgraded to revision 10422:a886bc3ae924 ), and have found that an NGS training workflow that one of us set up and published is no longer accessible - we now get a stack trace when we try to run it (screenshot attached) ; if we try to save to file, we "get page not found" from the browser, but no errors reported in web logs, or Galaxy log as far as we can see Is there any way we can recover the workflow ? How to avoid this happening in future upgrades ? This time it is not a major problem, however we would not want this to happen to production workflows. Should we save-to-file on all workflows as a precaution before an upgrade ? (Would that help ? ) The workflow included steps as below. Grateful for any suggestions. Cheers Alan McC First Part : checking GC content *Upload the sampling.fasta file or get it from the shared data in Galaxy. *Use geecee from EMBOSS *Remove beginning (Text manipulation), first line *Convert as tabular (Text manipulation) or cut (Text manipulation) *Histogram (Graph/Display Data)on col2 *Compute data (Text manipulation) (data4 convert; col2>0.2) *Count data (statistics on col3) If it is worth it we can remove the sequences which have a too low GC content 3 Second part : sequence length *Compute Sequence length (FASTA manipulation) *Summary Statistics (Statistics)on col2 *Filter by length(FASTA manipulation) ; 800 *Line/world/character count(Text manipulation) *Blastn against fungi db : yeast, only one hit to show (advanced options ) *Count the lines to know how many sequences have a hit . (Text manipulation) 4 Bonus track : removing sequences with low GC content *Select (filter and sort) on data 6 where matching = True *FASTA-to-Tabular (FASTA manipulation) the input file sampling.fasta (2 col for the title) *Join two datasets(Join, Subtract and Group) on the columns c1 *Tabular-to-FASTA (fasta manipulation) of the previous results. *You can see how many sequences you took away (click on the dataset name in History) and it should correspond to the number of True in Count . 5

Tophat for Illumina - built-in dog genome mislabelled
by Court, Michael 10 Oct '13

10 Oct '13

Hi, I minor annoyance that I had found with the current implementation of "Tophat for Illumina (version 1.5.0)" in the public usegalaxy.org site: When you submit sequences for alignment, the dropdown list of available genomes gives 2 dog genome choices - BUT both are labeled the same - "Dog(Canis lupus familiaris): canFam2". After trial and error I found that the second (lower on the list) choice is actually "Dog(Canis lupus familiaris): canFam3.1". Hopefully this can be corrected at some point - maybe when the next release comes out from the Broad. Michael [cid:image002.png@01CEC5C0.75D35560] Michael H.

Trouble viewing History from a particular laptop
by Olivia Choudhury 10 Oct '13

10 Oct '13

Hello, I am a graduate student in the University of Notre Dame. I have installed a personal instance of Galaxy and have been developing tools there as a part of my research. Everything worked well on my laptop until recently, when I could not view the 'History' panel, no matter which browser (Firefox, Chrome, Safari) I used on my laptop (Windows 7 OS). Everything works absolutely fine and I can view 'History' when I am using a desktop or any other laptop. I have checked this across different operating systems and also ensured that no changes were made with the Firewall setup of my laptop. I have attached a print screen of what the Galaxy page looks like. It would be great if I could get some help with this. Thanks a lot in advance, Olivia

Problems processing histories existing on galaxy before the changeover
by Elwood Linney 10 Oct '13

10 Oct '13

Is anyone who had developed histories on Galaxy online before the changeover getting red error messages after the changeover for tophat or cuffdiff processing? I have now tried a few times to move forward without luck and will remove at least one of my histories and start all over again just in case there is some kind of mismatch in the processing. Before I remove them all and start them all over, I would appreciate knowing if anyone else has identified where the block is. Elwood Linney

Online galaxy turning everything red on RNAseq steps
by Elwood Linney 09 Oct '13

09 Oct '13

Hello, I have been waiting a few weeks to process some RNA seq datasets but woke up this morning with lots of steps red. I thought it just might be because of the movement of the system but I processed steps for some histories and everything has turned red. I also noticed that online Galaxy now has RNAseq steps separated into two sections--does this have something to do with the problems? el linney Duke University Medical Center

Empty bowtie2 output
by Mikel Egaña Aranguren 09 Oct '13

09 Oct '13

Hi; I'm trying to use the bowtie2 wrapper but it generates and empty output with the "no peek" sign. I have sucesfully recreated the analysis with the same datatsets on the shell, so it must be something to do with Galaxy, but I don't know where to look at. Any clues? Thanks I'm using bowtie2-2.1.0 and Galaxy: changeset: 10421:a477486bf18e branch: stable tag: tip user: Nate Coraor <nate(a)bx.psu.edu> date: Thu Sep 26 11:02:58 2013 -0400 summary: Bugfix for tool-to-destination mapping, tool ids are lowercased but the mapping id was not lowercased -- Mikel Egaña Aranguren, Ph.D. http://mikeleganaaranguren.com

Galaxy available disk space bug
by Itys Comet 08 Oct '13

08 Oct '13

Hi everybody, Despite I purged all data from my Galaxy account and double checked that my account is actually empty by looking at Saved Histories/Advanced Search/status:all, my account is indicating that I am using half of it (as indicated in User/Preferences). Moreover, this is preventing me to actually use more than half of my account showing that it is not a display problem. It is also not a refresh rate problem since this problem started several months ago. Could you please help me with that? All the best, Itys -- Itys COMET, Ph.D. - Helin Group BRIC - University of Copenhagen Ole Maaløes Vej 5, DK-2200 Copenhagen N, Denmark Phone: +45-353 25602 Fax: +45-353 25669 Email: itys.comet(a)bric.ku.dk Web page: http://www.bric.ku.dk/research/Helin_Group/

replace function on galaxy
by Xianrong Wong 08 Oct '13

08 Oct '13

Hello, I have been using the compute function in galaxy to replace sequences with delimiters for processing my reads. I realized that the replace "code" in compute no longer works. Is there any other way to replace sequences with delimiters? Jose

How to lauch bulit cluster on Cloudman?
by Yan He 08 Oct '13

08 Oct '13

Dear all, I just established Galaxy Cloudman on Amazon EC2. I created a cluster named "exon_capture" and uploaded a lot of data to it. After some analysis, I terminated the cluster. The second time I wanted to get access to the "exon_capture" cluster, I created a new instance under the "exon_capture". However, under this instance, the "access galaxy" button is in grey and not active. I tried several time, but the button was always in grey. Does anyone know what's wrong? Did I miss something? It may be a very simple question, but it bothers me a whole afternoon. Thanks a lot! Yan
