v2.5

Changes since ARCADE 2.4

New features

• All modules of ARCADE (EyeServer, DaqServer, StimServer, ControlScreen)
  can now be enabled or disabled in the configuration (see ArcadeConfig).
  The function arcade/Core/launch_processes handles their startup based on
  the configuration and connects to the respective communication pipes.
• The configuration used for a particular session is now saved together with
  the behavioral data in the corresponding sessionLog folder.
• ARCADE can now be started with the path to a _cfg.mat file as an input
  argument skipping the MainScreen GUI for configuration. This makes it
  possible to start a task for a subject via a shortcut that calls
  start_arcade.bat
• SquareWaveGrating stimulus with anti-aliased bands and a circular mask
• StimServer v1.3.1.3:
  - anti-aliased Ellipse and Rectangle stimuli with support for outlines
  - support for swapping stimuli (drawing order)
• The new binary EyeLinkServer replaces the TestEyeServer and
  EyelinkEyeServer. This adds several new features:
  - A separate GUI for displaying the current eye position and the
  monitored screen locations
  - Speed: the EyeLinkServer can monitor many screen locations (~100)
  - Simulation mode: When no Eyelink system is connected, the GUI will
  act as a mouse simulation
  - Extandable: Due to a flexible pipe command interface additional
  features can be added in future releases (e.g. non-circular target
  windows)
• Support for MATLAB > 2014a.
• NidaqServer: added support for PCIe-6251, PCIe-6321 and PCIe-6323
• ARCADE sends a [0 1 0] eventmarker sequence at beginning and end of a
  session. This can be used to synchronize different recording systems, e.g.
  Eyelink and TDT Sys3.
• For testing a task script, the simulate_trial function will create all
  editable variables from a _cfg.mat file in the MATLAB workspace as well as
  a valid TrialData struct.

Changed features

• All user-facing functions and classes have extensive documentation of all
  relevant methods and properties.
• ControlScreen:
  - The GUI has been made more compact and resizable such that other
  windows can fit next to it.
  - The trial error legend now displays the correct labels that were set
  in MainScreen/configuration.
• ARCADE will now use the matlab.exe from the Windows PATH environmental
  variable. This is usually the one that was installed last. Tested versions
  are 2014a and 2018b Update 2
• Gammatron stimulus:
  • The drift direction is now configure via the sign of the temporal
    frequency
  • A temporal frequency of 0 will create a static Gammatron.
  • The phase offset can now be set in degree
  • The edge of the circular mask is now anti-aliased

Deprecated features

• The following stimulus properties are deprecated and should not be used
  anymore:
  • Rectangle.color (use Rectangle.faceColor instead)
  • Rectangle.alpha (use Rectangle.faceAlpha instead)
  • Circle.color (use Circle.faceColor instead)
  • Circle.alpha (use Circle.faceAlpha instead)
  • Gammatron.direction (use sign of Gammatron.temporalFrequency
    instead)

Fixed bugs

• CalibrateEyelink:
  • The last position of the Eyelink calibration and the first position
    of a validation sequence was not rewarded.
  • The CalibrateEyelink sets the screen_pixel_coords variable of
    Eyelink to [-w/2 h/2-1 w/2-1 -h/2] with w and h being screen width
    and height, respectively. It is recommended to the same in the
    final.ini file on the Eyelink PC.
