matlab packages and scripts:

• io64 installation: download the io64.mexw64 module and move it to a directory in your MATLAB path (e.g., c:\cog2000\Cogent2000v1.29\Toolbox in the case of the USD PSYC 770 standard Cogent 2000 64-bit Windows installation). Next, download the inpoutx64.dll module and move it to the C:\windows\system32 directory (i.e., This module must reside in the Windows system PATH).

• Psychtoolbox 3 (http://psychtoolbox.org/download.html)

• GStreamer

• Matlab's GUI Toolbox (https://www.mathworks.com/matlabcentral/fileexchange/47982-gui-layout-toolbox)

IMPORTANT: as of 29.07.2020, the GUI toolbox malfunctions in matlab 2020a. Please avoid using this or later versions.

VStim code important notes:

• In VStim: if you want to configure computer specific values (e.g. the port number of the used by parallel port), you can use the file ‘NET\PCspecificFiles\VSConfig.txt’, and change a VStim object property’s value by adding ‘property = value’ (notice the space before an after ‘=’). e.g. to change port number to 3BC write “parallelPortNum = 956” (value given in decimal not hexidecimal).
• to see where the main NET dir use NSKToolBoxMainDir=fileparts(which('identifierOfMainDir4NSKToolBox'));
