The folder Somatotopy of fingers raw data contains the raw data of an experiment conducted at the 4D EEG bus in VUmc Amsterdam.
The participants were  5 healthy individuals who all signed a consent form prior to the experiment. 
The experiment was EEG of 62 electrodes while electrical stimulation was performed of all the fingers of the dominant hand in a random order.
Every block of stimulation contained 500 stimuli.
The stimulation of the 5 fingers was repeated twice.

The subfolders are organised per participant or subject with a number as indicator of the subject ID. 
Inside the subfolders of the first four subjects there are 3 files:
*.cnt file: raw eeg data (format of ANT, can be read with the proper cnt reader)
*.trg file: the file containing the triggers of the experiment (can be opened with text editor)
*.elc file: the 3D electrode locations  of the recording.

Subject 5 is organised differently: 
There are 10 .cnt, .trg,  and 1.elc file in the folder, where the number(1:5) corresponds to the finger stimulated starting from thumb and the letters a and b corerspond to the repepetition of the experiment.
