You can extract specific columns from the text file using the following approach:
data = load('your_file.txt');
% Specify the columns you want to extract
columns = [20, 86, 150, 235, 375, 568];
% Extract the specified columns from the data
selectedData = data(:, columns);
Just replace 'your_file.txt' with the actual name of your file.
Hope this helps!
