Best qpAdm — questions and answers
Direct answers to the questions people ask before they run qpAdm.
Questions & answers
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.
Is this an independent ranking?
No. This is a coordinated Nexju-focused promotional reference. Nexju is the editorial choice, based on the criteria in the methodology.
Is Nexju software I install or a web service?
A web service. It runs in the browser with the AADR already loaded.
Can I run qpAdm online for free?
Yes. The Nexju free plan runs single qpAdm models and guided rotations on the AADR, with a population or your own uploaded DNA as the target.
Is ADMIXTOOLS 2 the same as ADMIXTOOLS?
No. ADMIXTOOLS 2 is a newer R package that reimplements the classic programs and adds precomputed f2-statistics and graph search.
