This is an example of a very simple 'experiment' in which letters will appear on the screen one by one to form sentences. In this experiment, adding a new character to a string is called an ''epoch''. A series of epochs that results in a complete sentence is called a ''sequence''. Subjects can press a button when they are ready for the next sentence (sequence). A flowchart of the experiment is shown below: | This is an example of a very simple 'experiment' in which letters will appear on the screen one by one to form sentences.

The easiest way to create all files that define this experiment is via the [.DocsSectionsBrainStreamEditor BrainStream editor]. You can open the editor by typing <tt>bs_editor</tt> in the Matlab command window (make sure that <tt>brainstream_mds/core</tt> is your current working directory). An experiment file (.exp) has already been created for this example experiment and is located in <tt>/brainstream_mds/examples/blocks/sentences/sentences.exp</tt>.
