I have a tab-delimated tabular file (indicated below) including information about the atomic positions of nucleotid bases. My question is that how can i get first 10 lines of every 20000 lines in a datasheet has 10^7 lines. Basically, is there any script for such a purpose ?
BaseAtomNumber atomic distances NumberofNeighbour IndexofAtom
1 1.94895 655 153
1 2.34545 566 543
Many Thanks in advance for your help !
