Importing data
The data used in this notebook is hosted on NYU BOX. Permissions are given upon request.
Install the BOX app from here
Set an environment variable with name
MEG_DATAto the path of the Data folder e.g.,C:\Users\user_name\Box\MEG\Dataor `C:\Users\user_name:nbsphinx-math:Box\Data
MATLAB setup
Make sure that:
Fieldtrip is installed in MATLAB
Add to MATLAB path the custom-made functions for NYUAD MEG lab found here
Each experiment run using the KIT system generates a .con file and two or more .mrk files.
[2]:
%% Attention task pipeline for external noise reduced data
MEG_DATA_FOLDER = getenv('MEG_DATA');
% Set path to KIT .con file of sub-03
DATASET_PATH = [MEG_DATA_FOLDER,'attention-task\'];
%THis needs fixing to sav eproperly
SAVE_PATH = [MEG_DATA_FOLDER, 'attention-task\'];
SUB_ID = 'sub-01\';
ATTEND_RIGHT_CON = [DATASET_PATH, SUB_ID, 'attention_attend_right_01.con'];
ATTEND_LEFT_CON = [DATASET_PATH, SUB_ID, 'attention_attend_left_01.con'];
% Pipeline Configuration
APPLY_FILTERS = false;
The Attention Task experiment was coded with the following trigger channels
Trigger information: KIT channel indexing starts with 0 while MATLAB indexing starts with 1, so ch224 on KIT is ch225 in MATLAB
There is four trial types coded on KIT trigger channels (in KIT indexing):
Attend left and target appearing right triggered on channel 224
Attend left and target appearing left triggered on channel 225
Attend right and target appearing right triggered on channel 226
Attend right and target appearing left triggered on channel 227
We can now perform the preprocessing of the data. Two .con files have been acquired, the first one is when the participant was attending the right side and a second one when attention was drawn to the left side.
