I have a file with 500.000 columns and 300.000 lines. The format is like that:
ColXX ColWW ColQQ ColTT ... ColEE
H1 G1 H1 K1 ... L1
G1 H1 K1 L1 ... O1
Based on the first line information, (ColXX to ColEE), what is the best method to take specific columns from a file and print on another file?
I tried to invert and take lines. But to go back to original file I need to invert again. Can anyone help me please?
Thanks a lot!
