    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)

    Error: Segment join failed with err = -11


    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:

    What parameters did you use in your command line input?

      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

        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.

          Could you share which gene is incorrectly annotated because I have the same problem but I have no idea how to find the incorrectly annotated gene?

            Advanced Sequencing Platforms Tackle Neuroscience’s Toughest Genomics Problems
            by SEQadmin2



            Genomics studies in neuroscience face a special challenge due to the brain’s complexity and scarcity of samples. Mapping changes in cell type and state using conventional next-generation sequencing methods remains challenging. Advances in technologies like single-cell sequencing, spatial transcriptomics, and long-read sequencing have opened the door to deeper studies of the brain and diseases like Alzheimer’s, amyotrophic lateral sclerosis (ALS), and schizophrenia.

            Cancer Drug Resistance: The Lingering Barrier to Rising Survival
            by SEQadmin2



            Cancer survival rates have significantly increased in the last few decades in the United States, reaching a combined 70% 5-year survival rate by 2021. Behind this number, there are years of research to find new therapies, drug targets, and early detection methods. But there is one core challenge that keeps slowing down these advances, and it’s about drug resistance.

            There is no single reason why many patients don’t respond to treatment as expected. Cancer is...

            Reply to Nine Things a Sample Prep Scientist Thinks About Before Sequencing
            by GATTACAT
            Love this - good data definitely starts from good input, and poor input can only give relatively poor data. I particularly like the mention of Nanodrop/absorbance based methods for quantification. It's such a toss up if you'll get an accurate reading or what amounts to a randomly generated number, and a lot of library/sequencing related issues can be traced back to poor quant.
