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
