Cufflinks Help
by Thomas, Mervyn G. (Dr.) 16 Oct '13

16 Oct '13

Hi All, I am trying to analyse some human RNA-seq dataset which is in BAM format to generate FPKM values using cufflinks. The ensembl group have aligned the data using BWA 0.5.9 to generate these BAM datasets. I realise that TopHat alignments are optimal for Cufflinks, but is it possible for me to use cufflinks or some other tool to derive FPKM values from BWA aligned reads? I tried using cufflinks on one of the BAM files but got an error: Error running cufflinks. return code = -11 Command line: cufflinks -q --no-update-check -I 300000 -F 0.100000 -j 0.150000 -p 8 /galaxy-repl/main/files/006/853/dataset_6853120.dat The additional output was: cufflinks v2.1.1 cufflinks -q --no-update-check -I 300000 -F 0.100000 -j 0.150000 -p 8 I have sent it to the galaxy team and awaiting their reply. Any thoughts about how I can go about analysing this data. Best wishes Mervyn Dr. Mervyn G Thomas BSc, MBChB, PhD Academic Foundation Doctor School of Medicine University of Leicester UK

Hello, I am trying to use the genome Annotation tool Augustus on my locally installed copy of Galaxy. After loading the data file, all analyses stop and deliver the following: error an error occurred with this dataset: /bin/sh:1:augustus: not found python: can't open file: '/extract_features.py': [Errno 2] No such file or directory Python is installed on my system (Ubuntu 12.04, Python 2.7.3) It must be something very basic I'm missing, but more basic are my linux skills… Thanks a lot Claudio ~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^ Claudio Slamovits, Canadian Institute for Advanced Research Department of Biochemistry and Molecular Biology Dalhousie University 5850 College Street, Halifax, Nova Scotia B3H 4R2, Canada Lab Webpage: http://slamo.biochem.dal.ca Lab: (902) 494 7894 Office: (902) 494 8825 Fax: (902) 494 1355 ^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~^~ "Reality is what it is, not what you want it to be." - Frank Zappa

Dear Dannon, I built a new cloud Galaxy instance today. Would you please tell me how to transfer given accounts from an old Galaxy to this new one? This is old Galaxy: http://galaxylocal.genenetwork.org:8080/ This is new Galaxy: http://galaxyclass.genenetwork.org/ Thanks a lot. Lei Yan Center for Integrative and Translational Genomics UTHSC

Jing If I have a Galaxy dataset, do you think it is possible to develop a pipeline that can Megablast from Shotgun data for: DNA gyrase only Ribosomal ITSinternal transcribed spacer only Cytochrome RecA Pol As well as filter all model organisms?

Importing reference genome into Galaxy for Tophat2
by Stanislas Werfel 15 Oct '13

15 Oct '13

Hi, I am new to the field of RNA-Seq analysis. I'd be very greatful if somene could help me with the following issue: I'm using the Galaxy Main plattform and would like to run Tophat2 on RNA-Seq data from rat. However in Main under Tophat2 there are only built-in human and mouse genomes, while a lot more genomes are vailable under Tophat for Illumina. I tried to import the rat genome sequence using the built-in UCSC Table browser, however I only managed to get a full genome as one FASTA file with all the different sequences. After mapping to this genome I can't see any hits when I click "display at UCSC main" on accepted hits. So I assume that the mapped reads do not conform to the official reference rat genome (rn5). So how can one solve this isse? -Is there a way to import a proper genome for use with Tophat2? Ideally directly indo Galaxy without prior download. -If not, how does Tophat2 differ from "Tophat for Illumina". Can one also analyze non-Illumina data with that? As I understand it Tophat2 is faster than the previous version? Thanks in advance for any help.

miRNA-seq help
by Gabriel Calvin 14 Oct '13

14 Oct '13

Hi, I'm new to Galaxy and am trying to view several miRNA datasets as a differential expression. The pipeline I'm using is Bowtie for Illumina (paired-end run) > SAM-to-BAM > ? > xls. The references I used with Bowtie are a mature miRNA fasta and a piRNA fasta and the reads are 30nt in length. So, my questions are: Is this the proper pipeline? How do I go about converting the BAM into a xls file viewable in Excel? Thanks!

New cuffdiff- no result files
by Johanna Sandgren 11 Oct '13

11 Oct '13

Hi, I have this week used the new wrapper version of Cuffdiff that you provide that should now include replicate information in output. But there is no resulting files created. Why? I get all the results in the right panel as usual and they are green (no error message) but the they are all empty.. I use bam-files and cuffmerge files that I have gotten result from before (both in spring and during summer- when you upgraded cuffdiff version). I attach below info for one resulting output.
