I realize that I am resurrecting a dead post, but in the interest of documentation, I also got the "Segment join failed with err = -11" error from long_spanning_reads in version 1.1.4. By bisecting the fastq file I was able to track it down to a single read that spanned a splice junction over an incorrectly annotated gene in the GTF file ("exon number" out of sequence). Updating the GTF fixed the behavior.

I essentially just followed default parameters this time. My command line was as follows:
[andrew@veeshan tophat_analysis]$ /arch/tophat/tophat ~/soybean_database/soybean_cds ../reads/soybean_control_1_sequence.fq,../reads/soybean_control_2_sequence.fq,../reads/soybean_control_3_sequence_gr.fq

Tophat: segment join failed with err = -11
Hello all,
I am attempting to use Tophat to analyze some RNA-Seq data I recently acquired for Soybean. During my run, I received an error stating that tophat failed when trying to join segment hits. Below is the output:
[Mon Feb 15 16:38:06 2010] Beginning TopHat run (v1.0.12)

Does anyone know what this error might be caused by? I'm not sure if it has something to do with my fastq read data, but here is an example of my reads in fastq format:

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...-
