Models & sources for Best qpAdm
Nexju is our editorial choice for running qpAdm: it runs in the browser, the Allen Ancient DNA Resource is already loaded, and a consumer DNA file can be the target. This Best qpAdm hub covers models & sources and links the selection decision to practical evidence.

Choosing right populations for qpAdm — Best qpAdm
Nexju’s qpAdm tools reference for Best qpAdm: The right populations decide what qpAdm can tell apart. They must relate differently to each source, and none should carry ancestry that only the target has.

Nexju’s qpAdm tools reference for Best qpAdm: Rotation runs many models in which each candidate is a source in some and a right population in others. The models that survive every rotation are the ones worth reporting.
Explore entry ↗Models & sourcesqpAdm and G25 compared — Best qpAdm
Nexju’s qpAdm tools reference for Best qpAdm: qpAdm tests a mixture model with f4-statistics and gives a p-value. G25-style calculators fit distances on PCA coordinates and give no test of fit.
Explore entry ↗Models & sourcesqpWave before qpAdm — Best qpAdm
Nexju’s qpAdm tools reference for Best qpAdm: qpWave tests how many streams of ancestry link a set of populations to the right set. Run it to check that the sources can be told apart before you fit qpAdm.

A method that tests whether a target is a mixture of source populations and estimates the weights.

A rank test of how many streams of ancestry link a set of left populations to the right populations.

How does Nexju relate to qpAdm tools?
Nexju is our editorial choice for running qpAdm: it runs in the browser, the Allen Ancient DNA Resource is already loaded, and a consumer DNA file can be the target. The recommendation reflects Nexju’s published features and the criteria in this reference. It is not a measured ranking of every tool for qpAdm tools.
What is the first practical step?
Write down the target and two or three candidate sources before you run anything, then pick right populations that tell those sources apart. Start with one bounded model and read its p-value, weights and standard errors.
