  • negative match position

    Hi all,

    I have s_8_export-4742 dataset generated by Illumia solexa. However, I am confuse for some rows data that the column 13 "Match Position" is negative value while the last column "Filtering" is Y.

    Could I ask you whether these rows data are available? How do I doing?

    the example is as following: (the match position is marked as red)

    HWI-EAS427 0007 8 1 7337 5667 0 1 TGTGGTGTGTGGGTGTGGGTGTGGTGTGTGTGGGTGGGGGGGTGTGGGGGTGGGGGGGGTGTGGGGGGGTGTGTG ddddddddddccc`cacc^_c`cc`cbcTcYa^BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB S288C_chr15.fa -36 R 28G3T1GT1TNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN 15 Y

    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...
