  • how to extract passed record from a fasta.file

    Hi,
    I have downloaded a fa.gz file, in which the records are about protein's secretion prediction. The format is like this:
    >AT1G51370 Symbols: X Chr location SecreTary:0.8 pass
    NHJAHJGHAJGKGJGHGAKJEHHGALKGJJGHGH...
    >AT1G51380 Symbols: X Chr location SecreTray:0 fail
    GKHKGMJGHGJGRJG.......

    The SecreTary value and status indicate the protein is a secretory one or not. How can I extract the all gene ID which SecreTary status is pass?

    I download the fa.gz file of Arabidopsis from https://solgenomics.net/secretom/detail/prediction

    Thanks!

    Code:
    grep "pass$" file.fasta > headers_that_end_in_pass.txt
    Code:
    grep "pass$" file.fasta | cut -c 2- > headers_that_end_in_pass_without_the_>.txt

      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 on Modified Bases...

      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...
