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 BS_INIT marker, first the [[BrainStreamBuildingExperiments#SecUserFun|user defined variables]] All_Pictures and Pictures are initialized. Then the function load_pictures() is executed, which loads all pictures that are needed for the experiment and stores them in the variable All_Pictures. Finally, the content of the user defined variables is copied to the [[BrainStreamImportantConcepts#SecVariables|global variables]] with the put statement.
