  • Help:how to extrcate information from the output file of Novoalign mapping tools

    Hello, Everyone,
    I want to extrcate some information from the output file of NonoAlign mapping tool, the output file format is FASTQ format, it likes this:
    @HWUSI-EAS1522 100625:1:1:1290:9446 # 0/1
    CGTCTCGTCTCGTCTCGTCTCGTCTCGTCTCGTCTA
    ################################ QC

    I have 2 questions:
    *The first question is what's the detail meaning of number in the first line (HWUSI-EAS1522 100625:1:1:1290:9446 # 0/1)?

    * The other question is how can I get the tab-separated files without headers containing four coulumns( 1 chr of reads; 2 the start position of the mapped read; 3 the stop position of the mapped read; 4 the strand information) which were extrcated from the output files of NovoAlign mapping tools.

    Thank you very much!

    Are you sure this is not the input format? I've never used Novoalign, but when mapping you normally use fastq as input and SAM/BAM as output (as is stated on the novoalign website as well...) A SAM/BAM holds mapping information such as your requested parameters, the fastq obviously doesn't.

    what's the detail meaning of number in the first line
    This is information about the the generated read such as machine, run, flowcell, lane, tile and paired-end/single-end.

    how can I get the tab-separated files without headers containing four coulumns
    SAM output will contain such information.

        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...
