Hello Geert,

For the best results, especially for SNPs, you will want to map directly to the 
target genome. The genome Galaxy is using is the same primary human genome the 
GATK team also uses - the 1000 genomes build 37 -> "hg_g1k_v37". Click on the 
GATK links from one of the tools to see the details. GATK provides liftOver 
files between the the genomes, and you could install and use these with the 
liftOver tool, but not for BAM datasets. Inputs are BED, Interval, GFF. (BAM -> 
SAM -> interval).

GATK also provides indexes (lifted) for hg19, but Galaxy does not provide an 
hg19 genome that is sorted appropriately for GATK, or at least not yet. RNA-seq 
tools and most other tools up until now required sorting in one way, and now 
GATK requires sorting in another, but keeping the database dbkey the same is 
important for visualization and other functions. It can get complicated when 
moving between tools in a history. We will likely have some 'best practice' 
solutions soon, but for now, use the 1000 genomes build to keep it all simple:

Human (Homo sapients) (b37): hg_g1k_v37

The good news is that installing this genome has been greatly simplified. The 
genome and indexes are now available on an rsync server.
You can simply download and add the genome directory and all the contents. You 
will still need to create the .loc file entries but the rest is done.
http://wiki.g2.bx.psu.edu/Admin/Data%20Integration

The "dbkey" is "hg_g1k_v37"

Hopefully one of the options works out for you!

Hi All,
   Is it possible to link to compressed files in a Galaxy data library?
We receive all of our NGS data in bz2 or gzip format for obvious
reasons, just wondering if I have to decompress it on the filesystem
before I link to it or not.  Thanks!

Great advice Sean!

Jianguang, this is the correct analysis - mapping the data to test the
actual insert size of the library as sequenced. The experimental notes
at SRA are just a starting place, the data is truth. A sample through
TopHat itself might produce more precise results. I suspect the coverage
on your top Blastn HSP is not complete, breaking off where it hits a
splice. And that you have some bias for sequences/hits that cross
junctions near ends. But overall, none of this would likely make that
much of a difference in the analysis as a whole.

Good luck!

Dear All,

I have some paired-end datasets to be analyzed, but I am not sure about their 
Mean Inner Distance between Mate Pairs.

Can I convert these paired-end datasets into single-end ones and use them as 
single-end dataset as follows?

1) Use the tool "Manipulate FASTQ" to convert the sequence of reverse reads 
into its reverse-complement counter part, so that all of the reverse reads 
actually become forward reads.

2) run Tophat on the manipulated datasets as single-end ones.

Thanks.

Jianguang,

This is not recommended. The value of the paired relationships would be
lost. Using an estimated Mean Inner Distance is a much better solution.
This is keeping in mind that testing different values may be necessary
to obtain the optimal results for any dataset.

Your situation about the reported vs actual sizing is not unique and
does not mean that the data is poor (when considered as a single
factor). Searching an online NGS website such as seqanswers.com about
the topic will being up several threads where this is discussed. Should
you have outstanding concerns about this particular parameter, please
consider contacting the tool authors at tophat.cuffli...@gmail.com for
advice.

Best,

Hello Mahtab,

Some vcftools are in development status on our test server under "VCF
Tools" at:
http://test.g2.bx.psu.edu/

Adding these and others (including the ones you mention) to the Tool
Shed is under consideration by the Galaxy team, but a firm timeline is
not set at this time. If your interest is in adding these to the Tool
Shed, they would welcomed. Another option is to check in with the
galaxy-...@bx.psu.edu development mailing list to see if any other
developer/group has something they could submit to the Tool Shed. Please
do not cross-post this thread, though, but instead create a brand new
message/thread with the relevant details and request (e.g. not a reply
with a new subject line or an added email).

Our primary investment at this time has been in the GATK pipeline. There
are differences in the way vcftools vs GATK works, so its not an exact
1:1 mapping of functionality, but you may be able obtain the results you
need by using the NGS: GATK Tools (beta) variant utilities
(CombineVariants, VariantEval, etc).

The GATK tool set is under active development and wrappers for these can
be found in both galaxy-central and galaxy-dist at bitbucket in various
stages of stability. Where to pull from depends on the tool (the version
will be the same for some in both locations, but this can change over
time) and your desire/tolerance to work with tools that are undergoing
change.
http://bitbucket.org/galaxy/galaxy-dist
http://bitbucket.org/galaxy/galaxy-central

Hopefully this provides some useful choices,

Hello Jianguang,

In simple terms, "No" produces a strict alignment and "Yes" produces a
more permissive alignment.

The option 'Allow indel search:' is a way of allowing for variability in
your data (presumably biologically valid) to not be interpreted as
mismatches or gaps. Mismatches/gaps in an alignment lower the overall
score and can lead to alignment failures. The default for this parameter
is "Yes" with value of 3 for insert/deletion length in Galaxy (allowing
for simple nucleotide polymorphism variability up to a single codon, per
position, in either the query or target). All values can be modified.

If this interferes with your data mapping accurately, then it could be
disabled by setting the parameter to "No". A test comparing the two
alternatives on a sample would be a good way to see how this single
change affects your particular sample. Good questions to ask: What reads
do not map when the stricter alignment rules are applied? Do any reads
map with a change in specificity? Do you agree with the results?

Hopefully this helps!
