BrainStreamPlugIns: Difference between revisions

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:

|-

!colspan="5"| '''Main Actions Table'''  

|}

<br />

|-

!colspan="3"| '''Main Dictionary Table'''

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):

|-

!colspan="5"| '''Imported Actions table'''

|}

<br />

|-

!colspan="3"| '''Imported Dictionary table'''

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:

|-

|-

| <strong>marker <br /></strong> || <strong>time <br /></strong> || <strong>function <br /></strong> || <strong>All_Pictures <br /></strong> || <strong>Picture </strong>  

|-

| end || EVENT || show_picture || get || 'end.jpg', get  

|-

|-

| <strong>marker <br /></strong> || <strong>type <br /></strong> || <strong>value <br /></strong>  

|-

| end || stimulus || 14  

|}

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.
