question about uploading data through URL method
by Xiangming Ding 20 Mar '12

20 Mar '12

Hi galaxy I am a new user of galaxy. i met a problem and didnot find similar question in FAQ. I wanted to upload the data from DDBJ DRA dataset to galaxy through UTL method. The file is around 800M. However after uploading, the FASTQ file was just around 2M. So I wanted know whether it is possible to upload a large file to galaxy through URL method? or I should download the file to my pc and then uploading to galaxy through FTP method. Thanks xiangmimg

Re: [galaxy-user] [galaxy-bugs] GI errors in the megablast table of results ?
by Guru Ananda 01 Mar '12

01 Mar '12

Dear Sandrine, Thanks for pointing out this issue. The BLAST databases we have on Galaxy are from last year, while those on NCBI website are the latest (Jan 2012). As pointed out on NCBI website ( http://www.ncbi.nlm.nih.gov/Sitemap/sequenceIDs.html), it appears that each time any change is made to a sequence/database, GI numbers change as well. This is perhaps why you're observing discrepancies in GI numbers and lengths between megablast outputs on Galaxy and NCBI. I'm currently in the process of downloading the latest BLAST databases from NCBI, and I'll let you know when they're available for use on Galaxy. Thanks for your patience, Guru Galaxy team.

SamTools Filter Pileup "Only report variants?" option is misleading
by Jesse Erdmann 07 Feb '12

07 Feb '12

In using the filter pileup tool we've discovered that the option "Only report variants?" will throw away lines that have indels provided that they do not contain any SNPs. For example the line: chr1 88427041 C 38 ..+1A..+1A.....+1A.,..+1A.....,.+1A,.,......,...,^~.^~,^~,^~, HHHHHFEHHHHHBFHHHHHHBFHHHEHHHAHHHFHG#E will not be included in the filtered results. At the very least we would recommend relabeling the option to "Only report SNP variants?" But it would also be helpful to include an option to filter for both SNP and indel variants.

Re: [galaxy-user] Disk Quote
by Zack Liu 07 Feb '12

07 Feb '12

Dear galaxy admins, I am working on a hi-seq project, where each file is ~ 50G. I have 8 of them. After I uploaded my files, I realized that I have reach my quote limit. Literally, I can't do any mapping or actions on these files since I have no disk space for it. I was wondering if there's anyway I can get more disk storage on galaxy. Thanks! Zack Liu

Gene and transcript names from Cuffdiff
by 杨继文 31 Jan '12

31 Jan '12

Hi all, I am learning how to use Galaxy to analyze my RNA-Seq data. After running cuffdiff, one of the files I got is "transcript differential expression testing". In this file, I can see " gene_id" is something like "XLOC_000001". I am wondering how I can find the name of differentially expressed genes and transcripts. Can anyone help me?????? Thanks in advance. Jiwen

Server Error when running workflow
by Stephen Eacker 31 Jan '12

31 Jan '12

Hello, I'm using Galaxy main to run some workflows. I'm running into a "Server Error An error occurred. See the error logs for more information. (Turn debug on to display exception reports here)" when running my workflow. I've seen that a number of others in the Q&A archives have had similar problems that were resolved by patches.

hi, Maybe anybody can give me a hint for the following problem... When I try to upload a fastq.gz file into galxy using url function the input os canceled with the following exception: An error occurred running this job: The uploaded file contains inappropriate HTML content I don't know where to start to have a look at. The upload of all other fastq.gz files from the same run works smooth. best stefan PS. Yes I know, the problem is really unspecific, sorry for that...

CloudMan Web Launcher / BioCloudCentral - Not showing public DNS
by mailing list 30 Jan '12

30 Jan '12

Hi guys, When I launch using BioCloudCentral (http://biocloudcentral.herokuapp.com) I noticed it doesn't show my public DNS. Even if I wait for a few minutes. For the "Public IP (Cloudman Console)" table cell, it just shows blank, and for the SSH access area is just says "ssh ubuntu@" It hasn't been a big deal because I just pull it from my EC2 console. But now I'm writing up some documentation for other researchers to use our application running on CloudMan, and it adds a lot of complexity to the documentation to tell them to log into the EC2 console, click on instances, copy the public DNS ... It would be excellent if they could just click a link from the launch page! Let me know if I can help with debugging. Thanks again, Greg
