[gmx-users] simulating several proteins

[Cristiano De Michele]

ok but after I generated two .gro files using genconf (or editconf I  
guess)
containing two identical proteins in different positions/orientations
how can I concatenate these two files in order to supply a unique .gro  
file to grompp?

thanks Cristiano
