mapping tags
by Soetkin Versteyhe
Dear all,
I would like to map (e.g. with Bowtie) collapsed sequences (tags) instead of individual sequence reads. Does anyone know if this is possible in Galaxy?
Thank you in advance.
Best regards,

Postdoctoral opening in College Park
by Charles Delwiche
I have a postdoc opening in my lab that could be an excellent opportunity for members of this list. The project is extremely cool, and will incorporate elements of ecology and systems biology. The position is open now, and I would like to fill it ASAP.
Charles Delwiche
Genomic basis of species diversity and ecosystem functioning
We seek a postdoctoral scholar to collaborate on a project funded by the U.S. National Science Foundation to study the evolutionary basis of species diversity and ecosystem functioning in freshwater green algae. The successful candidate will take intellectual lead on the genomics portion of laboratory and field experiments that will (1) determine how much genetic differentiation is required for species to stably coexist, and (2) determine how mechanisms that allow for coexistence also impact community-level processes such as primary production. The candidate will also pursue his or her own research interests within the broader context of the grant proposal.
The candidate will work in Dr. Charles Delwiche's lab at the University of Maryland – College Park, and will collaborate with researchers in the labs of Drs. Bradley Cardinale (an ecologist at the University of Michigan) and Todd Oakley (a phylogeneticist at UC-Santa Barbara).
The position requires a Ph.D. in the biological sciences, bioinformatics, or a related field. Experience with high-throughput sequencing, sequence analysis, algal/plant biodiversity, or RNA biology are desirable.
This is a three-year position, with the initial appointment being for one year and renewals contingent on successful progress in research. The starting salary will be $ 42,000 with full benefits.
The University of Maryland is located in College Park, a suburb of the Washington, D.C. Metropolitan Area, and provides a vibrant cultural and academic environment with easy access to a vast array of Federal research facilities.
The position is available immediately. To apply formally, send a curriculum vitae, the names of 3 references, and a brief statement of how your research goals fit with research on algal biodiversity, systematics, and evolutionary biology to: aaalgeee(a)gmail.com

Re: [galaxy-user] Unable to run SICER or Find Peaks
by Daniel Blankenberg
Hi AP,
Please keep all replies on list, this will allow the community to assist and benefit from these correspondences.
SICER requires BED input. To go from BAM to BED:
1.) Convert BAM to SAM
2.) Convert SAM to Interval (Convert SAM to interval)
3.) Convert interval to BED(6+). This can be done by implicitly (by selecting the Interval dataset, which will be marked with '(as bed)' in the SICER input box) or by clicking on the pencil icon and explicitly converting uder the section "Convert to new format".
Please let us know if we can provide additional assistance.
Thanks for using Galaxy,
Dan

Re: [galaxy-user] Names for genes in RNA-Seq analysis (Emilie Chautard)
by Emilie Chautard
Hi Olivier,
Did you try to run Cuffcompare (part of Cufflinks) on your results?
According to the Cufflinks manual (http://cufflinks.cbcb.umd.edu/manual.html
):
>Cufflinks includes a program that you can use to help analyze the
transfrags you assemble. The program cuffcompare helps you:
> - Compare your assembled transcripts to a reference annotation
> [...]
In the Galaxy version of Cuffcompare, I think that you can provide a
reference annotation file using "Use Reference Annotation:", which will be
compared to your results with Cufflinks.
It makes an "union" of the transcripts obtained with Cufflinks with the
annotation file (both in *.gtf format). You can then obtain a transcript
identifier for those already annotated.
It also provides a class code for the transcripts, which can inform about a
potential isoform for example.
Hope this helps.
Emilie

'Draw quality score Boxplot' error
by Caroline Proux
Hi,
I have illumina ChipSeq data and I want to use the "Draw quality score
Boxplot"
I run the"quality format converter (ASCII numeric)". But the "Draw
quality score Boxplot" do an error "An error occurred running this
job:Could not find/open font when opening font "arial", .."
where is my problem?
thank you so much

barcode splitter and clustering analyses?
by Simon Bulman
Dear Galaxy
we have a 454 metagenomic dataset. We have used barcode splitter to divide the dataset into it's constituent amplicons. We have also been using a clustering application (dnaclust) in Galaxy to subdivide the dataset by similarity. My question is; are there Galaxy tools to allow the combining, sorting and counting of these two outputs? For example, can each cluster - and then each sequence within that cluster - be given an identifier.... so that one can then split the output by barcode and summarise the data along the lines of amplicon/barcode X has X number of sequences within cluster 1, X number of sequences within cluster 2, ... etc? Am I making any sense?
This is the sort of problem that sounds like it is solvable in Excel and, indeed, a UK colleague of mine has been doing just this. But is there a straightforward means to do so in Galaxy? It is not obvious to me in the Filtering or Sorting tools.
best wishes
Simon

An update to Galaxy CloudMan
by Enis Afgan
A new version of CloudMan for running Galaxy on Amazon cloud has been
released today. Any new cluster will automatically use this version.
Existing clusters will have a link displayed at the top of the CloudMan
console offering to perform an automated update.
The new version brings the following updates/features:
- Added ability to specify a path where Galaxy is installed as part of user
data (using galaxy_home key). This allows custom Galaxy application to be
installed and picked up by CloudMan instead of the default one. This works
across cluster invocations as well as for shared clusters. For a complete
list of user data options see http://wiki.g2.bx.psu.edu/Admin/Cloud/UserData
- Use /etc/profile instead of /etc/bash.bashrc for system wide shell logins
- Support for 3.0 Kernel on Ubuntu 11.10 for SGE. Contributed by Brad
Chapman.
- Fix for SGE install after cloud-init has run and changed /etc/hosts
- post_start_service now runs if the script exists in the cluster bucket
even if no URL was provided as part of current user data
- Fix recognition of existing and attached file system volumes on instance

Question regarding: FASTQ Quality Trimmer
by Rahul Kanwar
Hello,
I am running Galaxy locally and it has been performing flawlessly! I
wanted to get more insight about this flag in the FASTQ Quality Trimmer
program:
Maximum number of bases to exclude from the window during aggregation
Does it mean the number of 5' bases to exclude while the doing the
trimming step [i.e. the sliding window starts this many bp after the read
start] ? I would really appreciate if someone could shed more light on
this. Thanks.
regards,
Rahul

Unable to run SICER or Find Peaks
by Anupam Paliwal
Hi,
I want to use SICER or Find Peaks for peak calling on GALAXY.
I am using my aligned ChIP-seq tag .BAM files. However for both the tools
the history is unable to pick the Bowtie-ligned SAM to BAM converted
files.
On the other hand, using MACS the same files are working nicely for peak
calling.
Thanks,
AP
