PennController().label( name ) (since PennController 1.1)
This is another way to assign a label to a PennController trial so you can refer to it in PennController.Sequence. It is most useful called on PennController.CheckPreloaded or PennController.InitiateRecorder since those commands do not take labels as arguments.
PennController.Sequence( "practice" , "preload-exp" , rshuffle("filler","test") ) PennController.CheckPreloaded( "filler" , "test" ).label( "preload-exp" )
Creates a trial labeled preload-exp checking that all the resources used in the PennController trials labeled filler or test are preloaded, and refers to its label in PennController.Sequence so it will be run before the filler and test trials, but after the practice trials.
