Well, for example, you would insert a molecule using gmx insert-molecule and specify the output file with the -o flag (we'll call the file conf1.gro) then, use gmx insert-molecule with conf1.gro as the input and specify the output file as conf2.gro, and so on... > for example I want: > insert molecule > remove the molecule if moving in the opposite direction There's no need to remove the molecule. The supporting information you mentioned says that the z-direction velocities were taken to be the absolute value, which gets rid of the problem of molecules traveling in the wrong direction (if the +z direction is where you want the molecules to travel towards). > insert > remove if > . > . > . > Do I need just to write it and copy it 3000 time or how can I do it ? Definitely do not copy it 3000 times. Use a simple for loop: https://www.cyberciti.biz/faq/bash-for-loop/ On the other hand, maybe you should contact the corresponding author of the paper you linked and ask if they have any advice or leftover scripts they used to set up the system. It will probably save you some time, although you won't necessarily learn something new.
