Create a variant

Why use a variant?

Variants are a great way to optimize your process workflow and memory. It is especially useful not to duplicate a whole study just to change a handful of settings.

You create a main study and then you can apply some small changes on your inputs. Then you can explore the impact of some changes on your study.

You can even create a large number of variants using Antares Craft to programmatically explore multiple configuration quicky.

Note

From the point of view of the user, a variant behaves just like a duplication of the main study, you can see the parameters, time series, modify the settings... However, internally it is stored as a difference from the main study to avoid duplication.

Create a variant

To create variant of a study first open your study and then click on the Create new variant button in the bottom.

It will open a pop-up where you can fill the information that you want. Then the new variant will be displayed inside the Study variant tree.

Then make sure you select the variant (or main study) and click explore to open the variant (resp. the main study).

Tip

You can create a variant of a variant and so on!

Note

Each variant has its own study ID.
