I am looking for a tutorial about f3 and f4 tests - with pictures :-). Do you know any ?
Did you try searching online? Please give us an idea on the effort you have invested in this.
thanks for your answer. Yes, I looked (several times I must say) and mainly find papers. I spent like ~30 minutes recently and maybe ~1 hour as a whole. Came across some workshops (http://gaworkshop.readthedocs.io/en/latest/contents/06_f3/f3.html) and papers but nothing looking like a presentation. Will read papers anyways but it helps me quite a few if there is a presentation out there.
If not, when I will make one, I will share it ...
