When i calculate distance i get a percent displayed, how to make coordinates with this percent to see which population it is more related to ?

I am not sure what you are asking. Perhaps I need a higher IQ. But I interpreted it as:

"When I calculate my distance from a population, I get a percentage displayed. How can I see how this population models in terms of other populations in my calculator?"

I assume you are using Vahaduo, and what you are referring to is one of the following:
1. Your distances in the 'Distance' section, that look like this
Distance to: Sacha_scaled
0.03367686 Lebanon_IAIII_Beirut
0.03632010 Italy_Roman_Empire_Rome_(Levantine_Profile)
0.03810363 Lebanese_Christian_Greek_Orthodox
0.03901910 Lebanese_Christian_Maronite
0.03954837 Hatay_MLBA_Alalakh
2. Your distances in the 'Single' or Admixture calculation sections, which look like this:
Target: Sacha_scaled
Distance: 2.6607% / 0.02660690 | ADC: 0.5x RC
40.4 Lebanon_IAII_Beirut
20.0 Italy_Roman_Empire_Casale_del_Dolce_(Anatolian_Pro file)
16.6 Anatolia_MLBA_Kaman-Kalehoyuk_(low_res)
8.4 Greece_BA_Minoan_Petras
7.4 Italy_Roman_Empire_Rome_(Levantine_Profile)
7.2 Israel_IBA_Yehud

For either of these, if you would like to see how a specific population stacks up in terms of other populations, you can:
1. Copy the name of the population you are trying to inspect
2. Go to the 'Source' tab and "Ctrl+F" that name
3. Cut (copy + delete) that coordinate from the source sheet, and move it over to 'target'
4. Run it as you would any other 'target'

Thanks, but i am not looking for that. So if i well understood the percentage i underlined and putted in bold is the part that don't match completly with the population written right after. I would like to extract the part that doesn't match, to know which population is closer to it

You wouldn't be able to do it with G25 because it uses coordinates but you can do it with calcs like Eurogenes K13/K15 for example and simply compare your component scores with the closest population's scores you match. Then extract the differences in a base 100 percentage to find which population it is closest to.

But 2-way sorts of do that already as well. Let's say you match Austria first, 2 way will give you a list of Austria + something and if 2 way match is closer than Austria, it's tryng to fit that difference, except it's never gonna be perfect @0.00 because that population surely doesn't exist.

Thank you for the answer. It exactly answers the question from this thread's title (at least how I understood that question).

I learned to speak Titanese a while ago.

I do not understand what are you talking about in your post.

Update: Tita user name, now I get it. I am too new for you people.

And playing with this tool?:

I didn't see that one. Thank you.
