  • How to run KmerFreq

    Have anyone tried Correction package of SOAPdenovo? I input the fq file, but it alway said that fail to open file?

  • #2
    Dear Elisa,

    you have to provide KmerFreq with a text file containing the names of the sequence file(s), otherwise it will try to open every line as a file name.

    So like

    Code:
    KmerFreq -i filenames.txt -o kmer_table
    Enjoy!

      I have put the name of file in the txt file like this:

      /diag/home/jjin/oil_palm/raw/DNA1.fastq
      /diag/home/jjin/oil_palm/raw/DNA2.fastq

      However, it still display error for the second file:

      quality cutoff: 5
      seed length: 17
      output kmer index?: no
      file format: fq
      >>>>>>>>>>hash initializing<<<<<<<<<<

      in /diag/home/jjin/oil_palm/raw/DNA1.fastq
      file of the reads - /diag/home/jjin/oil_palm/raw/DNA2.fast - opening failed.
      spend total time 3919

      Can anyone give me some suggestions?

      Thanks!

        I met the same problem as yours. Just add an 'return' at the end of second line of the input list file. It will be fine! Hope this will help you!

          I don't want to sound like a jerk, but did you make sure the path and permissions were correct?

            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...
