BAM files
by Edward Dudley 20 Apr '11

20 Apr '11

Hi - I have a set of 454 reads that have been trimmed and converted to BAM format using Galaxy, and I can visualize the alignment with E. coli genomes using the UCSC browser. Problem is, I'd like to display the alignment in Artemis, but Artemis doesn't seem to want to read the .BAM file downloaded from Galaxy; I can import my genome sequence but when trying to import the BAM a blank window with "message" in the header keeps popping up. Anyone else tried to do this, and is there something about the Galaxy BAM files that Artemis doesn't like? Thanks. Ed

Re: [galaxy-user] downstream analysis of cuffdiff out put

Vasu, Please reply to the mailing list as emails to individual Galaxy developers often get lost, and there are others on the list that might be able to help you or benefit from this discussion. Now, to your question: you're using the wrong GFF filtering tool, which is an easy mistake to make as there are many of them. You want to use Filter and Sort --> GFF --> Filter GTF data by attribute values list. Using this tool, I was able to filter dataset 11--a GTF file produced by Cuffcompare--using a Cuffdiff isoform expression file (dataset 10) on transcript_id. I've shared the modified history with you. Best, J.

Map with Bowtie
by Sher, Falak 18 Apr '11

18 Apr '11

Hi Colleagues, I mapped illumina sequences using Bowtie on Galaxy server, I could not locate the information, like how many there were total reads and in what percentage they are mapped with mouse genome etc (samples were from mouse). Help and suggestions are greatly acknowledged, Thank you for attention, Falak

database on the cloud
by Randall, Thomas (NIH/NIEHS) [C] 18 Apr '11

18 Apr '11

I set up a galaxy instance on the cloud, but got the following error when trying to convert a bed file of hg18 coordinates to fasta sequence with the "Extract Genomic DNA" tool as a test of the functionality of this instance: No sequences are available for 'hg18', request them by reporting this error. Where did I go wrong? Likely I would get a similar error for other databases and indexes I might need and the instructions on the bitbucket site does not cover this (https://bitbucket.org/galaxy/galaxy-central/wiki/cloud). Otherwise this is a very nice setup. Thomas Randall, PhD Bioinformatics Scientist, Contractor National Institute of Environmental Health Sciences P.O.

Normalization an dplotting of RPKM/FPKM after cufflink
by vasu punj 17 Apr '11

17 Apr '11

Hi, I want to include the following discussion in my message regarding use Bam files of Tophat to visualize reads either in IGV or Galaxy or other tools. I want to find out if I can plot RPKM/FPKM normalized values after running differential analysis in Cufflinks. On the seqanswer (http://seqanswers.com/forums/showthread.php?t=9947 ) there is a preliminary discussion about this how we can plot RPKM values to show the differential abundance in samples. Do we have any of such functionality in Galaxy? alternatively, I would like to have suggestions on the topic especially to normalize per million reads. Thanks. --- On Tue, 2/22/11, Jeremy Goecks <jeremy.goecks(a)emory.edu> wrote: From: Jeremy Goecks <jeremy.goecks(a)emory.edu> Subject: Re: [galaxy-user] get wig file after tophat To: "David Matthews" <D.A.Matthews(a)bristol.ac.uk> Cc: "Baxter, Adam" <Adam.Baxter(a)uncc.edu>, galaxy-user(a)bx.psu.edu Date: Tuesday, February 22, 2011, 11:30 AM All, For visualization, Galaxy now provides a built-in browser called Trackster. Trackster can visualize BAM files--as well as the junction file produced by Tophat and the GFF files produced by Cufflinks--and also provides coverage/summary information for all datatypes (see attached image). You can start using Trackster by going to the Visualization --> New Track Browser to set up a browser and add tracks. Alternatively, you can click on the Trackster icon in a dataset to visualize the dataset in a new or existing visualization (see attached image). Thanks, J.

Best Ying Quoting David Matthews <D.A.Matthews(a)bristol.ac.uk>: Hi, You can get an equivalent visualisation from the IGV viewer by the Broad Institute - its under IGV tools and generates a tdf file from bam or sam files.

Cheers David On 21 Feb 2011, at 21:44, Jeremy Goecks wrote: Hi all, Ann is correct - Tophat does not produce .wig files when run anymore. However, it's fairly easy to use Galaxy to make a wiggle-like coverage file from a BAM file: (a) run the pileup tool on your BAM to create a pileup file; (b) cut columns 1 and 4 to get your coverage file. A final note: it's often difficult to visualize coverage files because they're so large. You might be better off visualizing the BAM file and using the coverage file for statistics. Best, J. Hello, I think I know the answer (sort of) to this question. This may be because newer versions of tophat stopped running the "wiggles" program, which is still part of the tophat distribution and is the program that makes the "coverage.wig" file. A later version of tophat might bring this back, however - there's a note to this effect in the tophat python code. So if you can run wiggles, you can make the "coverage.wig" file on your own. A student here at UNC Charlotte (Adam Baxter) made a few changes to the "wiggles" source code that would allow you to use it with samtools to make a "coverage.wig" file from the "accepted_hits.bam" file that TopHat creates. If you (or anyone else) would like a copy, please email Adam, who is cc'ed on this email. We would be happy to help add it to Galaxy if this would be of interest to you or other Galaxy users. If there is any way we can be of assistance, please let us know!
