Hi all,
I got the following error infomation during Tophat mapping
An error occurred running this job: Job output not returned by PBS: the output
datasets were deleted while the job was running, the job was manually dequeued
or there was a cluster error.
Please let me know what's wrong.
Help
I have similar problems. My tophat job was sent 6 hours ago. Now the job is
still waiting to be run.

Hi,
My cufflinks jobs sat in the queued state for 12+ hours so I restarted them
this morning. They've been in the queued state now for about 2-3 hours. Any
idea why?
Here's a link to my
Hi,
I am analyzing my RNA-Seq data. After running cuffdiff, I got a list of
differentially expressed transcrpts or genes.
As far as I know, log2 value = fold change. However, there are minus values.
Is this possible?? log2 value can not be minus. Did I miss something??
Looking forward to you
Hi all,
I read one paper "Differential gene and transcript expression analysis of
RNA-seq experiments with TopHat and Cufflinks".
They say the procedure for RNA-Seq analysis is
Tophat-->cufflinks-->cuffmerge-->cuffdiff
But what I normally do in Galaxy is
Tophat-->cufflinks-->cuffcompare-->cuff
Hi all,
After mapping, I used IGV to have a look at the mapping. There are a lot of
mapped reads without pair reads. Should I keep these reads? or Is this a
problem for cufflinks analysis?
What I tried is:
1. BAM to SAM
2. Filter SAM: set Read mapped in a proper pair to Yes.
The result is tha
Hi,
After mapping RNA-Seq paired end reads with Tophat, I can see that most of
reads fall into the right regions. However, I still can see lots of reads
mapped to non-coding region (the locations where the reads are mapped to don't
contain exons).
I am wondering if these "non-coding reads"
Hi,
I am very confused by my mapping. Please help me figure out what's wrong with
my operation.
I got Illumina Hiseq 2000 paired end reads (mouse), and I used Tophat to map
these reads.
After mapping, I used IGV to have a look at the mapping.
I can see that some of the reads fall into exons o
Hi,
I am uploading files to Galaxy via FTP. The speed is only 30kb/sec.
Is there something wrong with my operation? or is this just normal due to
Galaxy's work load?
Looking forward to your answers.
Thanks

Hi all,
I have paired end RNA-Seq reads ( Illumina Hiseq 2000) in seperate files.
Before mapping, I need to trim the reads.
My questions is : Do I have to join pair end reads before timming, and then
split again for Tophat???
Lookiong forward to your answers.
Thanks

Dear Galaxy team,
I found glalaxy (website) is running really slow today. I just did some text
manipulations over a very small file. It takes a long time till the gray colour
(waiting) turns into yellow (running). Now the jobs are still waiting to be
processed (gray colour).
I have to analyz
Dear all,
This might be a silly question, but I couldn't figure it out by myself :-((.
Could you please tell me how I can find out how many reads have been mapped to
the genome after running Tophat for pair end RNA seq data?
Thanks in advance.

Hi all,
When mapping pair end RNA-seq reads using tophat, we need to type in "Mean
Inner Distance between Mate Pairs". In galaxy, we can read the following
information:
This is the expected (mean) inner distance between mate pairs. For, example,
for paired end runs with fragments

Dear all,
I am using Galaxy for RNA-Seq analysis. I expect two lists: differentially
expressed transcripts and differentially expressed genes. In these two lists, I
would like to see the gene name, gene
Dear all,
Today I used Tophat to map the reads from RNA-Seq, and had a look at the
results using "visaulization" function. In some regions I can see splice
junctions calculated by Tophat, but I don't see any reads mapping to this
region. Is this a bit strange? I thought "splice junction" is calc
Hi all,
First I would like to thank you for your fast replies to my questions.
As you know, at top right corner of Galaxy window, there are records of the
history size and how many percentage of memory space has been used. I found
that the number in the records only increases, but doesn't decreas
Hi All,
I got a bit disappointed when I failed in the following operation which seems
to be simple.
I uploaded mouse annotation/reference gene sets (GTF format) to Galaxy. The
file is located at ftp://ftp.ensembl.org/pub/release-65/gtf/mus_musculus/.
As far as I know, GTF file is t
Hi All,
Today I have problem to use FTP to upload data to Galaxy. I used Filezilla
software and the server name "main.g2.bx.psu.edu", but I can not connect to the
server. Something wrong with my operation?
Also, when I tried to get data from Biomart to Galaxy, I got the error warning

Hi all,
I am learning how to use Galaxy to analyze my RNA-Seq data. After running
cuffdiff, one of the files I got is "transcript differential expression
testing". In this file, I can see "
gene_id" is something like "XLOC_01". I am wondering how I can find the
name of differentially expre
