  • tophat error = -9?

    I ran tophat on some data yesterday, and got the following (error at bottom):


    matt@matt-desktop:~/Desktop/data/bowtie_trim_final$ tophat -o bowtiecap01 -r 100 --solexa1.3-quals -p4 mm9 s_5_1_sequence.txt s_5_2_sequence.txt

    I saw another thread about this error, with the suggestion that the fasta file was bad, but this file is being reconstituted during the analysis. Is this actually a problem? or is there something else wrong here?

    Thanks for any help,

    Matt

    Too many reads

    Hi,

    I had the same problem. I have splitted my reads and then it worked !
    I first had more than 400 millions 50 bp reads, It worked with 1/5. I didn't try other split size.

      Essential Discoveries and Tools in Epitranscriptomics
      by seqadmin




      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...

      Current Approaches to Protein Sequencing
      by seqadmin


      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...
