Dear Singh,

I have tried both of the commands but still get no results.
My file is something like this:
Code:
....

.
.
GWA quasiparticle energy with Z factor (eV)
(I need 98 lines after the above line)
...

*many lines after, than again*
GWA quasiparticle energy with Z factor (eV)

Do you have any suggestion?

Thanks,
Nu
