[gmx-users] topol files

[Alex]

Hello gromacs user,

I have for peptides, each have a .gro file and a topol file. Using the
"cat" command I can easily merge their .gro file to have a box contains
four separated peptides (means I do not want to make a new big peptide but
seprated), but merging their topol files is not a easy task for me, I was
wondering how I can merge their toplo files? The OPLS-AA is used as force
filed for all of them.
Thanks.

Regards,
Alex
