    Do you mean keep the left end, or keep the right end?

    What is your favourite scripting language (since there are lots of options here, Perl, Python, Ruby, etc)?

      i use perl.. keep the right end.. and trim the left end.. i already trimmed adapters..

        perl is OK
        fastx_trimmer provided by FASTX_Toolkit may be faster.

              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...
