Downloading files
by KNIGHT M.R.
Is there any way of downloading processed files by e.g. FTP, rather than
"Save as" in the web browser? I have a large (9.6Gb) BAM file to
download, and downloading it via the browser seems unstable for some
reason. Thanks, Marc.

Re: [galaxy-user] Dataset not appearing as available input to SAM analyses
by Jennifer Jackson
Hi Clare,
Galaxy is fairly transparent, so this occurs sometimes and can mean that
either the server is very busy or there is another problem, perhaps with
the dataset.
Please note that mpileup is not supported yet, just pileup, although
this is on our short list of to-do upgrades. If you used mpileup, this
could very likely be the root cause of the tool error ("server error").
You can track the upgrade to mpileup through this ticket:
https://bitbucket.org/galaxy/galaxy-central/issue/524
To troubleshoot a pileup file:
1 - double check the format of your data again the specification as
outlined on the tool form for "NGS: SAM Tools -> Generate pileup from
BAM dataset".
2 - try running the file type assignment again the job again to double
check against a transient error.
If pileup was used and the cause of the error is still unclear, we take
a look we can provide feedback. Please share a link to your history
using "Options -> Share or Publish" from the top of the history panel,
generate a share link, then email that back to me directly. Please note
which dataset presents the problem and confirm that "samtools pileup"
was used.
Thanks!

Removing low quality reads
by Getiria Onsongo
Galaxy Users,
I would like to filter a .bam file to remove reads with low mapping quality,
especially ambiguously mapped reads (MAPQ = 0). I can easily do this using
the command line version of samtools as shown below.
samtools view -bq 20 hba1.bam > hba1_MAPQ20.bam
None of the options available under "NGS:SAM Tools" (e.g., Generate pileup
and Filter SAM) provide an option for removing reads with low mapping
quality. The history shown in
http://main.g2.bx.psu.edu/u/onsongo/h/obtaininghighqualityreads
shows the results I would like to obtain.
Data 2 shows the results of Picard tools SAM/BAM Alignment Summary
Metrics<http://main.g2.bx.psu.edu/tool_runner?tool_id=PicardASMetrics>
on
hba1.bam which contains reads with MAPQ values less than 20. As shown in
this summary html, PF_READS_ALIGNED = 775 and PF_HQ_ALIGNED_READS = 241.
Data 4 shows the results of Picard tools SAM/BAM Alignment Summary
Metrics<http://main.g2.bx.psu.edu/tool_runner?tool_id=PicardASMetrics>
on hba1_MAPQ20.bam which contains only reads with MAPQ greater than or
equal to 20. As shown in this summary html, PF_READS_ALIGNED = 241 and
PF_HQ_ALIGNED_READS = 241.
Is there a way in Galaxy to filter a bam file to remove low quality mapped
reads similar to using the samtools command line alternative shown above?
Thanks,
Getiria

Expected Transcriptome BLAST
by Colicchio, Jack M
Hey,
Jack Colicchio here, a PhD. student at KU. I am about to get an illumina Next gen transcriptome data setthat I would like to align and quantify against a list of expected transcripts from Mimulus guttatus. The expected transcripts are in .gff format, and I was wondering how I could get that file uploaded to you're website to allow me to align my transcriptome against. I successfully uploaded the .GFF file, and can view it on your site, but do not know how I could blast my .fastq data from illumine against this file.
Thanks,
Jack

Re: [galaxy-user] Names for genes in RNA-Seq analysis
by Jennifer Jackson
Hello Olivier,
When deleting data, it takes the server a short amount of time to
refresh. It may take a bit longer right now since many people are
performing this action at the same time.
For the RNA-seq analysis question, reference annotation GTF files are
used by the Cuff* programs. (These are different than the result GTF
files produced by the programs). For reference annotation GTF files,
there are many sources, including Ensembl and UCSC. Here are links to a
tutorial and an FAQ that can help with your usage question.
http://main.g2.bx.psu.edu/u/jeremy/p/galaxy-rna-seq-analysis-exercise
http://main.g2.bx.psu.edu/u/jeremy/p/transcriptome-analysis-faq
But, there are many small details to running the tools to get the
optimal results. These types of questions concerning functionality are
best directed to the tool authors at tophat.cufflinks(a)gmail.com
Take care,
Jen

Cannot get rid of custom build error
by James Vincent
Hello,
I've tried to create a custom build (starting from the trackster page)
and clearly made some mistake. I get a NoConverterException error
which is almost certainly my fault putting something wrong in.
However, now the Custom Builds page shows this error and I cannot make
it go away.
I have a local install, have killed and restarted, logged in and out,
but still this error stays. I cannot try to enter another custom build
because there is nothing on the page except this error. Does anyone
kow how to get rid of this? Any help in getting around this error are
appreciated.

fastq groomer
by arabidopsis
Hi all,
Fastq groomer has Solexa or Illumina 1.3+ as an input quality format. I
asked at the sequencing facility about their machine and output and they
said their format was Illumina 1.8+ (the newest). I tried to convert my
fastq file into Sanger by fastq groomer, using Illumina 1.3+ as an input
option and got all reads with quality of around 10... Does it mean that
Galaxy cannot be used on a dataset with 1.8+ encoding or something else was
wrong?
Thanks,
Slon

get data through FTP site
by Benoit HENNUY
Hello,
I uploaded (on Oct, 25) data through FTP site and I was not able to
retreiven them to include them in a history. I suppose that the files
should appeared in the FTP list under the Get data page.
THese data are named "P2 fastq .gz" files that I wold like to use in RNA
Seq workflow.
Thank you to help me to be able to use these data.

Re: [galaxy-user] Names for genes in RNA-Seq analysis
by Michael Gooch
Regarding the GTF files for cuffllinks, how do I obtain one for all
human mRNA that actualy contains gene names rather than accession
numbers. I went to the UCSC table browser but their files contain
accession numbers that I dont know how to decode en-masse.
