  • kmer counting software issue

    There are many kmer counting software. If just to find repeats, can I just use someone that can count frequency and can give the kmer position in the genome(or reads), and then align the high frequency kmers? Some software just output the kmer counts, I don't know which software can output the kmer position along with the kmer counts.

    You can always map the k-mers back to the genome with e.g. bowtie2..

      Thank you. I think mapping back is redundant because when counting it can also do that. I will try to find some other ways to do that.

        Saving positional information is a lot of overhead for k-mer counting algorithms so I'm not so sure it has been implemented in any of them..

          For bacterial genomes there is an old program which can do this for 8-14mer kmers called OligoCounter. Not useful for large genomes though (>50 MB?).



          Mapping back to the genome is probably a much quicker option.

            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...
