    TopHat "accepted_hits.sam" header line

    I am runing the TopHat. I found that the header line of the file "accepted_hits.sam"is as following:
    @HD VN:1.0 SO:sorted
    @PG TopHat VN:1.0.130

    The file "accepted_hits.sam" does not working for Samtools.

    I use the commond "./samtools view -S -t -X -o exampl.flag accepted_hits.sam", and got two errors:

    The tag [ID] required for [PG] not present.
    Segmentation fault..

    According to suggestions from nilshomer, I changed the line "@PG ID:TopHat VN:1.0.13). The first error is gone.

    So my problems:
    1) Why my file "accepted_hits.sam" without "ID:"?
    2) how to fix the second error?

    Thanks

    It seems that it is still not liking the "@PG" line. Can you make sure that they are TAB separated?

      Proteomic Platforms: How to Choose the Right Analytical Strategy to Improve Detection and Clinical Applications
      by SEQadmin2


      Proteomics platforms are evolving rapidly, with advances in mass spectrometry and affinity-based approaches expanding what researchers can detect and at what scale. As the field moves toward deeper proteome coverage and clinical applications, scientists face an increasingly complex landscape of tools. This article will explore how researchers are navigating these choices to find the right platform for their work.

      The systematic characterization of the human proteome has

      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...
