    You never know whether DNA sequences are forward or reverse until after you map them; the mapper will figure that out on a per-read basis. You don't need to do anything special.

    The usage is pretty straightforward:

    Index:
    bwa index ref.fa

    Map single-ended reads:
    bwa mem ref.fa reads.fq > aln-se.sam

    ...or, map paired reads:
    bwa mem ref.fa read1.fq read2.fq > aln-pe.sam

    started a topic bwa-mem Roche454

    bwa-mem Roche454

    Goodmorning,
    (sorry for my bad english), I would use bwa-mem to map sequences against human genome. I have the file fast.q of Roche454 Junior, in this there is not specified if the sequence is in forward or in reverse. In this case, what is the option which allows to use BWA-MEM?
    I really hope someone from seqanswer can help me.
    Thank you in advance.

    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...
