    Hola, amigo:

    Sólo a título de comentario. Ya en el mes de Marzo, Lucasz los incorporó a sus modelos. Tomó como referencia básica el I12032 con un índice genotípico de 0.17. Y los modelos I12162 e I12163 como referencias secundarias. El primero tiene como proxys: Alemania Occidental, Francia y Sur de Holanda. En el modo mixto es prácticamente germánico en un 83 pct. Aunque las tres referencias pueden utilizarse para obtener un modelo genérico de visigodo. Yo utilizaría única y exclusivamente como proxy de visigodo el de referencia I12032 aunque se trate de un modelo de referencia individual para incorporarlo de manera temporal a cualquiera de nuestros modelos basados en medias de población. Tan sólo es una sugerencia. En esto tú eres el maestro. Un abrazo

    This is in fact because, whenever you mix components from different continents into a G25 model, you should use scaled data, as mentionned by Generalissimo, the author of the tool ("when modeling admixture from outside of Europe always check the scaled data!"), otherwise you can get this kind of issue (like here North African ancestry showing up wrongly for French/North Italians)

    And indeed, when using same model using same populations but with scaled data we can see that North African (as well as Levant_Canaanite_MBA) is not showing up anymore for French/North Italians:

    Can you justify technically what you just said? Actually don't, I don't want this thread to become another annoying and pointless discussion about scaling.

    By the way, no, the author of nMonte isn't David. It's Huijbregts, and he never scales data. It was also Huijbregts who came up with this form of scaling, but he says it's so bad it should not be used. David tells people to use whatever makes sense to them.

    Now if you want to make your models, please go ahead, making a discussion on scaling discussion, no.

    I quoted David who can better than anyone else justify this technically so better you ask him directly…. But just looking at the results posted should be enough I guess.

    It really isn't.
    Please share models or don't bother with this discussion, because it will be deleted. This isn't a thread about scaling.

    Ok, understood... I just sent you a PM with an interesting sample.
