    PCA plots based on nucleotide word frequency (k-mer) of assembled contigs &/or raw re

    Which utility package (preferable web-based) is available to generate PCA plots based on nucleotide word frequency (k-mer) of assembled contigs &/or raw reads ??? I found R bit tricky and tough to handle...so any thing other than R or R with some really helpful guide is preferable...

    FactoMineR does a lot of great PCA things, and can fairly easily produce nice plots:



    According to the FactoMineR main page, there's also now Factoshiny, which provides a dynamic, interactive way to explore your data with FactoMineR:

    You're posting in a bioinformatics forum, and rubbishing the free software swiss army statistics chainsaw of R. Saying "R is too confusing, can you tell me how I can do [statistics] without using R" is unlikely to give you good results.

      No not at all rubbishing..sorry if I misunderstood...i just said as i am not a bioinformatician so i found it tough to use..anyway thanks for your suggestion

        Since this is one of the top hits while googling, thought I would leave here that CheckM with the tetra_pca command will do this:

          Beyond CRISPR/Cas9: Understand, Choose, and Use the Right Genome Editing Tool
          by SEQadmin2



          CRISPR/Cas9 sparked the gene editing revolution for both research and therapeutics.1 But this system still showed severe issues that limited its applications. The most prominent were the heavy reliance on PAM sequences, delivery limitations, double-stranded breaks that prompt unintended edits and cell death, and editing inefficiency (both in targeting and in knock-in reliability).

          Despite this, “CRISPR helped turn genome editing from a specialized technique into

          Proteomic Platforms: How to Choose the Right Analytical Strategy to Improve Detection and Clinical Applications
          by SEQadmin2


          Proteomics platforms are evolving rapidly, with advances in mass spectrometry and affinity-based approaches expanding what researchers can detect and at what scale. As the field moves toward deeper proteome coverage and clinical applications, scientists face an increasingly complex landscape of tools. This article will explore how researchers are navigating these choices to find the right platform for their work.

          The systematic characterization of the human proteome has
