T = readtable("data.txt");
T=T(:, 2:end)
T = 8×5 table
sub_id gender RT keypress cond ______ ______ ______ ________ ____ 103 1 9.1386 4 5 103 1 3.1832 8 2 103 1 2.6894 1 1 103 1 4.4707 9 8 103 1 3.0162 4 4 103 1 4.7932 3 3 103 1 2.9433 1 6 103 1 2.7987 3 7
x = table2array(T)
x = 8×5
103.0000 1.0000 9.1386 4.0000 5.0000 103.0000 1.0000 3.1832 8.0000 2.0000 103.0000 1.0000 2.6894 1.0000 1.0000 103.0000 1.0000 4.4707 9.0000 8.0000 103.0000 1.0000 3.0162 4.0000 4.0000 103.0000 1.0000 4.7932 3.0000 3.0000 103.0000 1.0000 2.9433 1.0000 6.0000 103.0000 1.0000 2.7987 3.0000 7.0000
