If you have known matches, you can 'paint' your DNA by assigning segments to specific ancestors or groups. For example:

If I share DNA with my mother's paternal cousin, then I know that I inherited all of these segments from my maternal grandfather.
Or if I've identified a number of matches who are related to each other, it's likely we have the same common ancestors (even if I don't know who yet)
In both these cases, grouping the match segments and colour-coding them helps me to build up a picture of my DNA, and means when I overlay new matches, I can immediately see how they fit in to what I already know.

This is pretty cool. Very useful for me actually to see what overlaps between certain family members.

It's probably an excellent tool, but I couldn't make head or tails of it.

As said I don't really get this. I created a profile and then tried paint a match. However I'm not sure how the group thing works. Do you have a separate group for each match? Or can you put all matches into one group ? If so how are the matches differentiated in the browser? I tried this with S then J and clicking just showed J with a large green square. I wanted to see S&J.

Interesting video,but it didn't tell me what I wanted to know.

If you add a new match you can choose to link it to an ancestor ("group") you already have.

I tried that. Painted a match S and added it to group N. Then painted match Jo and added it to N. Right clicking on the segment in the browser only Jo was given.Maybe because S and Jo were both in the same place on chr 10.

Yes, if matches completely overlap, you may not see them.
I have a part overlap with half of the underlying segment overlain by the one on top (one on top is at left).

So a complete overlap would be invisible.
If you have a segment wholly inside another one, I suggest you try deleting both, then put in the long one followed by the short one within it.

I guess using parents here is a bad idea? They take over all chromos? Only more distant matches are reasonable?
