Gitlab Repository Matrix

Description

The Gitlab Repository Matrix contains matlab files for the Matrix program. This program can present several sentences of five words each to a subject with a headset and keep score of the subject recalling the correct words. The program can mix sentences with noise and also vocode the spoken words and/or noise. The program can present Dutch and German sentences. The program can also present objects on a second screen to the subject. It can use an eyetracker to record the pupil size of the subject and it can use an event recorder to synchronize the sound-, screen- and eyetracker-data.

How to install the Matrix program

• Copy the repository to your computer in a directory
• Open the directory with the matrixprogram in matlab
• Make a directory 'C:\DATA\<your initials>\matrixtest\Results
• Make a directory 'C:\DATA\<your initials>\matrixtest\Sounds
• Copy the 'Sounds\NL' and/or 'Sounds\DE' or directory from \\mbcogro-srv.science.ru.nl\install\matrixtest
• Open the file 'matrix_main.ini'
• In the ini-file select the language under [global]
• In the ini-file select the hardware you will use under [hardware]
• You can customize the tasklist using the <loadfromfile> option under [tasklist] and specify the tasklist in a file named <Tasklist.ini>
• In order to customize the trial you can edit the file <..\matrix\trialPlayer\matrixTrialPlayerClass.m>

The ini file

The inifile contains info about:

• language
• paths
• filenames
• hardware
• tasklist

Use only: "strings", true or false or numerals.
Lines beginning with '%' will be ignored. Comments can be added after parameter by using brackets: (comments...)

Here is an example of an inifile:

[global]
language    = "NL" ("DE" or "NL")

[paths]
% settings is relative to the program home path
settings      = "\settings"
results       = "C:\DATA\RL\matrixtest\Results"
sounds        = "C:\DATA\RL\matrixtest\Sounds"

[sounds]
% all path are relative to the paths.sounds
sentencesDir  = "\Sentences"
wordsDir      = "\Words"
testlistsDir  = "\Testlists"
noiseDir      = "\Noise"

[DE]
listbase      = "olsa"
matrixfile    = "wordmatrixDE.txt"
noisefile     = "olnoise.wav"
nomspeechfile = "nomspeechDE.wav"
picturefile   = "matrixpicDE.png"

[NL]
listbase      = "nlmatrix"
matrixfile    = "wordmatrixNL.txt"
noisefile     = "dutchspeechnoise.wav"
nomspeechfile = "nomspeechNL.wav"
picturefile   = "matrixpicNL.png"


[hardware]
soundprocessor = true   
lsl = false
pupil = false
screen = false
soundProcessorType = "RZ6"  ("RZ6", "soundcard", "dummy", .....)
rz6DeviceID = "TST" ("TST", "EEG", "PAT", "VST", "ARM" or "None") 
secondaryMonitorIndex = 1 (1 or 2)

[tasklist]
loadfromfile = false
filename = "Tasklist.ini" (do not change)
