v2.6

[2.6.0] - 2022-04-07

NEW

• Added sleep.* and timeBEPeriod.* to arcade\Core. sleep( ) is a wrapper
  for Windows system call Sleep( ). timeBEPeriod enables/disables higher-
  precision multi-media timers via the timeBeginPeriod( ) and
  timeEndPeriod( ) system call.
• Added priority.* for managing the priority class of ARCADE processes.
  apriority.m simplifies the interface in ARCADE core functions. Essential
  ARCADE processes flipped in and out of high-priority state during the
  critical period of a running trial.
• User can add empty file called EyeServer_SetSampleMode.arcade to same
  folder as task file in order to optionally enable EyeServer's sample
  mode.
• StimServer v1.4.2.3: The deferred mode (groupStimuli) can now be canceled
  by using new cancel command or the StimServerEndDeferredMode event.
• EyeLinkServer v1.2.3.0: Support to receive samples for speed up,
  support for EndDeferredMode events
• The new add-on EditableVariableEditor contributed by Yufeng Zhang can be
  used to edit the editable variables in an existing configuration file (*_cfg.mat)
• NidaqServer 1.0.11.2 supports PCIe-6259

FIXED

• Issue 21
  Done by finding Matlab timers that were created by processManager and
  stopping them. NOTE that now command line output from sub-processes is
  no longer accessible without reading the ASCII log files.
• Issue 6. Gammatron
  radius sets properly.
• A bug in the ARCADE startup caused the seeds of the random number generator
  to be identical on a given day leading to identical random sequences.

v2.5.7

[2.5.7] - 2020-04-07

CHANGED

• StimServer v1.4.2.1: The window size of the StimServer stimulus screen in
  windowed mode is now 800x600 pixels. This prevents accidental switches to
  go unnoticed. Timing and performance in windowed mode are not reliable.

FIXED

• A bug process synchronization could prevent successful startup of ARCADE

v2.5.6

[2.5.6] - 2020-03-02

NEW

• StimServer v1.4.2: support for Gamma correction
• measure_screen_gamma.m: new script for measuring the screen gamma value

CHANGED

• EyeLinkServer 1.2.0.0: In and Out events are now mutually exclusive

v2.5.5

[2.5.5] - 2019-12-10

NEW

• StimServer v1.4.1.1: the Wedge stimulus can now be rotated via
  a LinearRange animation.
• NidaqServer v1.0.17.1: added support for PCIe-6351

v2.5.1

#[2.5.1] - 2019-06-07

NEW

EyeLinkServer v1.1.6.0: When both eyes are tracked, the eye used for
monitoring regions can be selected from the EyeLinkServer GUI. If only one
eye is tracked, the selected eye is displayed.

FIXED

EyeLinkServer v1.1.6.0: For binocular tracking, the current position was
sometimes switching between the two eyes at runtime, causing small eye
position jumps. This was fixed.

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.
