ArControl provides application, the ArControl Recorder, for recording data. See the demo Light_3 task. The data file is saved in a subject-specific location, as a single ASCII format file. This data can easily be translated into a Matlab MAT-file.

Data file location

Data files are located in ARCONTROL_PATH/data/PROJECT_NAME/SUBJUECT_NAME/YYMMDDhhmmss.txt.

Take the figure below for example. chen is the PROJECT_NAME. subj_1 is the SUBJECT_NAME. 171007212558.txt means 2017/10/07 21:25:58.

Data file format & convert to Matlab

The data file is an ASCII format file. Each record represents the Begin time and Duration time in millisecond. Take care that the configuration of Record Levels has direct effects on the data content.

This data file can be converted into a Matlab MAT-file. The code file can be found in RELEASE_PACKAGE/Covert2Matlab/BF_arc2mat.m
