First, you have to research the Clone Vat in your Research tab. Once you've done that, build a Cloning Vat in the Production tab, left-click to select it, then click 'Start growing' at the bottom of the screen. It will allow you to select the filled genome sequence you made.

Wow simple as this, thanks alot !
If you agree, could you explain me if there's a way to transfer my dead pawn's stats to my new clone, once grown up ?

To apply stats onto another pawn, you need to use a Brain Template. You can apply a brain template onto new clones, but you can only make a brain template from living beings (because the brain is biologically dead!).

To apply the brain template, you first need to research 'Brainwave scanning' - it's near the end of the mod's research tree. Once you've got that researched, build a Brain Scanner at the Fabrication bench. Select the colonist whose skills you want to preserve, then add a surgery bill to scan their brain.

Once you have the brain template, select a pawn and right-click it > Apply brain template. With the targeting cursor, select the clone you want to apply the template to.

NOTE: The template can only be applied to clones
NOTE 2: Once a clone has been brain templated, they can't be templated again

Wow thanks alot mate,
got everything I need now.
HF cloning ;)

One last thing that isn't immediately obvious from the mod description: You can apply brain templating to animals, too! It will preserve their training (like Hauling or Release), and you apply it to new cloned animals in the same manner as you do with humans.

I can not apply a brain pattern, I scanned it, but the clone in the operation section does not have the item "apply a brain pattern"

The brain templating isn't a surgical operation, because you have to use a specific game item (and surgeries are for generic types of items). Once you have the brain template, select a pawn and right-click the template > 'Apply brain template'. With the targeting cursor, left-click the clone you want to apply the template to.

I applied a brain template to a clone... and it didn't seem to do anything. The clone has the traits of the original (Industrious/Fast Learner/etc), but none of their skill levels. Passions are slightly different as well. I can edit all this with mods, but still... :(
