Re: [galaxy-user] Initial QC and grooming for Illumina HiSeq2000 paired end RNAseq data
Good Morning, I confirmed with Illumina that my reads are in Sanger FASTQ format and used edit attributes to change them to fastqsanger. Then I joined the forward and reverse and ran the FastQ Joiner and the FastQC on the joined data file. I'm getting the following error: ## odpath=None: No output found in None. Output for the run was: Picked up _JAVA_OPTIONS: -Djava.io.tmpdir=/space/g2main Started analysis of FASTQ Analysis complete for FASTQ Failed to process file FASTQ java.lang.IllegalArgumentException: No known encodings with chars 33 (Yours was ) at uk.ac.bbsrc.babraham.FastQC.Sequence.QualityEncoding.PhredEncoding.getFastQEncodingOffset(PhredEncoding.java:33) at uk.ac.bbsrc.babraham.FastQC.Modules.PerBaseQualityScores.getPercentages(PerBaseQualityScores.java:70) at uk.ac.bbsrc.babraham.FastQC.Modules.PerBaseQualityScores.raisesError(PerBaseQualityScores.java:164) at uk.ac.bbsrc.babraham.FastQC.Report.HTMLReportArchive.startDocument(HTMLReportArchive.java:194) at uk.ac.bbsrc.babraham.FastQC.Report.HTMLReportArchive.(HTMLReportArchive.java:59) at uk.ac.bbsrc.babraham.FastQC.Analysis.OfflineRunner.analysisComplete(OfflineRunner.java:157) at uk.ac.bbsrc.babraham.FastQC.Analysis.AnalysisRunner.run(AnalysisRunner.java:108) at java.lang.Thread.run(Thread.java:662) I thought that perhaps this was because I just changed the file format and maybe they really aren't in Fastqsanger format, so I: changed the format back to fastq, ran the groomer, joined them and then ran the FastQC and received the same error. I also tried to join them first and then run the groomer, but the files don't show up if I haven't changed the attributes to Fastqsanger (which makes sense if Galaxy only uses fastqsanger files). I'm not sure what to try next. Thank you Lindsey On Wed, Jul 4, 2012 at 3:53 PM, Jennifer Jackson j...@bx.psu.edu wrote: Hello Lindsey, Yes, you have this correct.

Re: [galaxy-user] Initial QC and grooming for Illumina HiSeq2000 paired end RNAseq data
Hello Lindsey, Would you please send in a bug report from the FastQC error dataset that resulted from the run where you included running the Groomer tool first? This will help us to track down the problem. Please be sure to leave all datasets in your history for this run undeleted and in the original history that they were executed in. If you need to undelete, use Option (gear icon) - View Deleted Datasets, the click on the links to undelete. We will need the original inputs and full path through tools run in Galaxy. http://wiki.g2.bx.psu.edu/Support#Reporting_tool_errors Please include this email address in the bug report notes if your Galaxy account uses a different one.
