In order to import a table, you only have to specify the reference to it in your main Actions table. A simplified example of an imported table is given below:

At the BS_INIT marker, the BCI experiment will be initialized and subsequently a BCI processing pipeline will be executed. Let's assume that inside this processing pipeline is a function that inserts a marker whenever a picture needs to be shown. The presentation of pictures is taken care of by the Pictures table (@Pictures):

At the start of each BrainStream experiment, the main experiment definition tables and all references to import-tables will be combined into one table, a process called table expansion. This means that all Action tables will be integrated into a single Action table, and the same is true for the DataSelection and Dictionary tables. Thus, in the example mentioned above, the expanded tables would look like this:

When the experiment is finished, you can find the expanded tables in the [.DocsSectionsLogFile Log file]. Additionally, if you are using the [[BrainStreamBrainStreamEditor|BrainStream editor]], you can view your expanded tables before running the experiment by clicking on the 'Expand table' button.
