PCA plots

PCA PlotsSee where your DNA sits among thousands of populations.

Place your own sample on an interactive principal component chart beside ancient and modern reference populations. Start from a regional preset, rotate it in 3D, find the populations nearest to you, and hand a cluster straight to nMonte.

What you can do

A PCA you can explore, not just look at

Presets to start from

Regional plots for Europe, West, South, Central and East Asia, and Africa, ready in a click, with room for your own sample.

Your sample, measured

Add your sample once it has G25 coordinates and see where you fall, how far you are from any reference, and which populations sort closest.

Clusters and neighbours

Group the plot with k-means or Ward clustering, outline each cluster, and list the populations and samples nearest to yours.

Straight into nMonte

Lasso part of the plot or pick a cluster and send it to nMonte as source populations, or save a cluster’s centre as a sample.

2D, 3D and any axes

Rotate the plot in 3D, choose which principal components sit on each axis, and export the chart as SVG or PNG.

AI analysis

With a plan’s credits, ask the AI agent what the clusters represent, where your samples sit and what to model next, then ask follow-up questions.

Getting started

Your first plot in three steps

  1. 1

    Upload your DNA

    Add the raw file from 23andMe, AncestryDNA, FamilyTreeDNA, MyHeritage, LivingDNA or WeGene, exactly as you downloaded it.

  2. 2

    Get G25 coordinates

    Run a G25-ready calculator such as Eurogenes K15; the coordinates come with the run.

  3. 3

    Plot and explore

    Open a preset or build your own, add your sample, and read the distances.

Presets

Start from a regional preset

Each opens a ready-made Global 25 plot that you can add your own sample to.

Questions

Frequently asked

What is a PCA plot?

Principal component analysis compresses genetic variation into a few axes, so populations that are genetically close sit close together. It is the quickest way to see where you fall among reference groups.

Is it free?

Plotting, adding your sample, saving and sharing are free. The AI analysis uses more Compute Credits than the free monthly allowance, so it needs a Basic or Pro plan.

Can I plot my raw DNA file directly?

A sample needs coordinates first. Running a G25-ready calculator such as Eurogenes K15 gives you simulated G25 coordinates at no extra cost, and HarappaWorld, Eurogenes and Dodecad results can be plotted in their own spaces.

How much can one plot hold?

Up to 100 reference groups and 500 of your own samples, drawn from thousands of ancient and modern populations.
