[galaxy-user] Cuffdiff errors

2012-08-16 Thread Yan He
Hello,

 

I am having a problem running Cuffdiff on some RNA-seq data.  I want to
compare 2 samples (A and B). I did Cufflinks and Cuffmerge before running
Cuffdiff. I ran Cuffdiff with the following options: Cuffmerge + Bowtie A, B
(sorted required by Cufflinks after mapped with Bowtie). But I got the
following error message:

 

An error occurred running this job: cuffdiff v1.3.0 (3022)

Re: [galaxy-user] Do I need to allow indel search?

2012-08-16 Thread Jennifer Jackson

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!

Re: [galaxy-user] Use Own Junctions or not

2012-08-16 Thread Jennifer Jackson

Hello Jianguang,

Junctions refer to known splice sites. TopHat has several options that 
work together to supply known junctions and to use them in various ways. 
This is used to direct splice identification. Given what you have 
explained about your experiment, I would not think this would be a 
desirable affect, so they are probably best left at default. Or, you 
could test to see the outcome. The parameter summary at the bottom of 
the tool form explains each and the manual can guide how to combine.


To do more research on this, the tophat.cuffli...@gmail.com mailing list 
is the definitive source, but there are plenty of prior discussion 
threads at seqanswer.com and other places. Try a search with tophat 
junctions or add in some of the parameter names to help filter through 
the results.


Best,

Jen

[galaxy-user] Counting intervals in one file overlapping intervals in another file - what are the hidden settings?

2012-08-16 Thread Mohammad Heydarian
Hi,
I am using the Count intervals in one file overlapping intervals in
another file tool (part of the bedTools package) to assess the number of
RNA-seq reads that map back to a specific region. (I am using this on the
Galaxy test server). I am finding that this tool returns many more reads
than it should.

In reading the bedTools manual, it seems like this tool is the windowBed
tool and it actually has many more parameters that are not shown on the
Galaxy interface. What are these (hidden) settings for these parameters
that are not shown?

Hopefully this can explain my incorrectly recorded reads.

Thanks in advance.


Cheers,
Mo Heydarian

[galaxy-user] Minimum length of read segments

2012-08-16 Thread Du, Jianguang
Dear All,

I am going to run Tophat with RNA-seq dataset to observe alternative splicing 
events. There is a parameter for Tophat: Minimum length of read segment. 
According to implemented Tophat options, the description for Minimum length 
of read segment is Each read is cut up into segments, each at least this 
long. These segments are mapped independently. The default is 25. The length 
of my reads is 36bps, should I change this parameter based on the length of my 
reads? How long should I input?

[galaxy-user] run Bowtie to estimate Mean Inner Distance between Mate Pairs

2012-08-16 Thread Du, Jianguang
Dear All,

In order to figure out the Mean Inner Distance between Mate Pairs of my 
paired-end RNA-seq datasets, I ran Bowtie (Map with Bowtie for Illumina) with 
both forward and reverse datasets and mouse mm9 as reference genome. Below I 
list the Bowtie output for only one pair of reads (I put the fields on the left 
side):


For the forward read
QNAME:   SRR322837.8.1
FLAG:99
RNAME:   chr1
POS: 163761156
MAPQ:255
CIAGR:   36M
MRNM:=
MPOS:163761301
ISIZE:   181
SEQ: NTGGATACTAGCCATAAATGAATT
QUAL:%(,,')(())@@@22358852@@@##
OPT: XA:i:1 MD:Z:0A35  NM:i:1

For the reverse read
QNAME:   SRR322837.8.2
FLAG:147
RNAME:   chr1
POS: 163761301
MAPQ:255
CIAGR:   36M
MRNM:=
MPOS:163761156
ISIZE:   -181
SEQ: TATTATGTCAATCTATGAAGAAGGACGGCGAGGTGA
QUAL:GDBE@BEEGDB=BD-=GEDDGGBGD8GB?
OPT: MD:Z:29A6  NM:i:1



Is the ISIZE the insert size? The difference between POS and MPOS is 145bp, 
which is 36bp shorter than ISIZE (181). My question is: if ISIZE does mean 
insert size, how should I convert INSIZE into Mean Inner Distance between Mate 
Pairs?



Thanks,

Re: [galaxy-user] copy number variation detcetion in Glaxay

2012-08-16 Thread Erik Garrison
Hi Mathew,

To clarify, freebayes is not designed to detect CNVs.  It can CNV
information detected in another method to correctly genotype at sites with
copy number variations.

If you have exome data, there is conifer
http://http://conifer.sourceforge.net/
conifer.sourceforge.net/ http://conifer.sourceforge.net/.

For more general applications, there is ERDS,
http://www.duke.edu/~mz34/erds.htm

I don't know if either of these will suit your needs.  I use the CNV input
methods in freebayes regularly for known, large variations in copy number,
such as are seen on mammalian sex chromosomes.
