Hello none of the recommendations had worked for me, has anyone found out what is the problem with error -11 and how to solve it?
thanks

see the Bowtie 2 Manual,
the section titled "The bowtie2-inspect index inspector"
here is a quote from the manual:
"bowtie2-inspect extracts information from a Bowtie index about what kind of index it is and what reference sequences were used to build it. When run without any options, the tool will output a FASTA file containing the sequences of the original references (with all non-A/C/G/T characters converted to Ns). It can also be used to extract just the reference sequence names using the -n/--names option or a more verbose summary using the -s/--summary option."

Originally posted by alabadorf View PostI encountered this error too and it was indeed related to a mismatch between the index and fasta file. Instead of rebuilding the index without random chromosomes, I used bowtie2-inspect to create a new fasta file from the index. The error went away.
The exit status code -11 corresponds to a segmentation fault suffered by the segment_juncs program, where I suspect it tries to find a fasta sequence but can't. The source of the error is actually in the SeqAn distribution, which they have bundled with the tophat release.
my reference file is :musref
my index file are : musref.1.bt2 musref.2.bt2 musref.3.bt2 musref.4.bt2 musref.rev.1.bt2 musref.rev.2.bt2
what command can help me create a .fa file?
Thank you a lot!Last edited by 1520191; 04-23-2014, 03:52 AM.

and the command I use is the following:
tophat -p 8 -G $DATA/mm9.mrna.10.31.gtf --prefilter-multihits -o $WDIR/tophat_$TAG --segment-length 12 --max-multihits 15 $BOWTIE/mm9 $FQFILE

I also get the error with the same ID, with a very established tophat 1.4.1.1
These are shorter reads I'm working with (25 bp), so I wonder it that is the problem?
I dug in the code a bit but couldn't find what exactly "-11" refers to. I wish there'd be a more verbose mode to tophat that would give more information on errors.
Anyhow, if anybody knows more about this, I'd love to know it.
PS yeah, and segment_juncs.log has no error at all (and it's the last log written). It looks like the program just stopped.

By random chromosomes do you mean scaffolds (eg chrG*)? Do you just remove all from ref.fasta and build your index from this? I thought I had them removed.
Does anyone know specifically what is causing the error?

Thanks Doris, I will try to rebuild the index and see if that helps. I will update the post accordingly.

I received the same error message, with Tophat 2.0.0 + Bowtie2.0.0.6,
but could fix it by correcting the Bowtie genome index, in my case hg19.
While the downloaded index contained the random chromosomes, the hg19.fa fasta file did not. After re-building the index without the random chromosomes,
the error message disappeared.
Hoping that this was helpful,
Doris

The error persists!
I am using the latest tophat version, but the error persists. I am also trying with the oldest version available in our system to see if that works.

Hi, Johnathon
Thank you for your rapidly replying and suggestion.
I am just trying by using the older version of Tophat and bowtie.
Sincerely,
Suimye

Sorry, I actually can't recall how I resolved this error, although I wasn't using Tophat v2.0 when I ran into it.
Maybe Cole, or another Tophat programmer could be of more help. It also might help if you posted more info about the run you were attempting to perform and what preceeded the error message.
Cheers,
Johnathon

I also got this message when Im running TopHat v2.0.0 (Bowtie version:2.0.0.5).
Do you have any solution for this error?

The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...-

Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...-
