  • How to extract those reads, that are not fully aligned in BLAST+?

    Hi there!

    Like the title says, How do i get those reads, that are not fully aligned in BLAST?
    Someone already tried it?

    What do you mean by fully aligned?

      If you aligned reads against a database, you will have to extract the identifiers of reads that did align to something first and then extract those reads from the original input file. There is no way to fully recover incompletely aligned query sequences from blast output (as far as I am aware).

        I've been doing something similar recently - mainly via awk command from a tabbed blast+ output and then using this file to filter an input sequence file.

        If you elaborate a little on what you are trying to do, I may be able to help.

          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...
