    pca

    hello every one,
    could you suggest me how to create 3d PCA plot with multivariate data as (need to plot PCA for samples not for genes)
    Code:
    example data:
    
    Genename   S1  S2   S3   S4   S5  S6    
    gene1    1 14.23 1.71 2.43 15.6 127 
    gene 2    1 13.20 1.78 2.14 11.2 100
    gene 3    1 13.16 2.36 2.67 18.6 101
    gene 4    1 14.37 1.95 2.50 16.8 113 
    gene 5    1 13.24 2.59 2.87 21.0 118

    Calculate the PCA (in R, the pca() function) and use a 3D plotting function (in R, the plot3d package).

      Nine Things a Sample Prep Scientist Thinks About Before Sequencing
      by SEQadmin2


      I’m not a sequencing expert. I’m a purification scientist who uses NGS to evaluate workflows my group develops. With this perspective, we think about the sample first and the NGS workflow second. The sequencer is an exceptionally honest reporter, but it can only report on what you give it, so whether you get clean, interpretable data from an NGS workflow is largely determined before you begin.


      Here are nine questions we think about, in roughly the order they matter, before...

      From Collection to Sequencing: Why Sample Preparation and Preservation Define Sequencing Data
      by SEQadmin2


      Data variability is still an issue in sequencing technologies despite the advances in reproducibility and accuracy of these platforms. But the problem does not originate in the sequencing itself, but in the previous steps, before the sample reaches the sequencer.


      The first step is collection, followed by preservation and sample preparation for analysis. Most scientists overlook those steps, but not being careful might just be skewing the experiment’s results.
