  • trimmomatic error correcting problem

    Hi all,

    I use trimmomatic to trim and error correct. Commands are as below
    trimmomatic PE -threads 16 forward.fastq.gz reverse.fastq.gz paired-1.fastq.gz unpaired-1.fastq.gz paired-2.fastq.gz unpaired-2.fastq.gz ILLUMINACLIP:/opt/Trimmomatic-0.32/adapters/NexteraPE-PE.fa:2:30:10*LEADING:3 TRAILING:3 SLIDINGWINDOW:4:15MINLEN:36

    When I take out the error correcting part (starting LEADING to the end), it was able to finish trimmomatic. When I include that part, it gave error. Please see below: Any one can help? Thank you!

    You should have a space between the different commands, and it looks like there isn't a space between the end of the parameters for the ILLUMINACLIP command and the LEADING command.

      Thank you for replying! I checked my commands and reran it. It did have space in between. And with space, it still shows errors:

        If you have a space and not a '*' before LEADING, you might have some kind of control character present, because trimmomatic seems to be interpreting your command as containing the characters '10*LEADING', which it doesn't recognise, and it is giving an error.

          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...
