subset in PLINK --hardy

[louise.b...@gmail.com]

Hello group, 

I have tried to perform --hardy on my dataset, but now I want only a part of my individuals at a time. 

Now i've done --within. This gives the same result als withou --within (Yes I've put a file behind it ;))

Then I found --keep-cluster. This made me happy because It had different results, But it gives me 22 out of 23 individuals in my file. 

And when I want a different cluster (offcourse with another file) It gives the error that no individuals are left. 

All files used are in the right format. 

I just really want to know what goes wrong. 

Thank you in advance
