There are two types of expressions in Biosphere2:
- Expressions that create new locations/vectors
- Expressions that transform locations/vectors
The usual workflow is that you first create a bunch of locations or vectors. In a second step you apply some transformation to them. And in a final step you do something with them. This is best shown by an example:
The result looks like this:

The goal of Biosphere2 is to provide convenient expressions for the creation and transformation step. What you then do with your final list of locations/vectors is up to you.
