  • what does "edit distance" mean?

    The BWA manual refers to "edit distance". What does this mean?

    It's the amount of difference between two sequences; your read, and your reference.

        Below is from BWA.aln documentation:
        "The maximum edit distance. This specifies a threshold of the maximum number of deletions, insertions, and substitutions needed to transform the reference sequence into the read sequence."

          In computer science-speak, it's the Levenshtein distance

            Recent Advances in Sequencing Analysis Tools
            by seqadmin


            The sequencing world is rapidly changing due to declining costs, enhanced accuracies, and the advent of newer, cutting-edge instruments. Equally important to these developments are improvements in sequencing analysis, a process that converts vast amounts of raw data into a comprehensible and meaningful form. This complex task requires expertise and the right analysis tools. In this article, we highlight the progress and innovation in sequencing analysis by reviewing several of the...

            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...
